Despite this usage, most of us know that randomness has something to do with probability, and that it often implies a lack of conscious intentionality. But what do mathematicians and scientists mean when they say something is random? Can a random process lead to an ordered, even predictable outcome? Is there evidence that God makes use of random processes to fulfill his creative purposes?

These are big questions, and we won’t address them all today. But I think randomness is an important topic to cover for two reasons: 1) it is integral to many processes in biology (and math, physics, chemistry, etc.), and 2) it is commonly misunderstood to be incompatible with Christianity.

As I said above, most of us know that randomness has something to do with probability. If you pick a card “at random” from a shuffled deck, you have a small probability of drawing an ace (4 out of 52, or a 7.7% chance). If you flip a coin, you have an equal probability of getting heads or tails.

Randomness also seems to imply a lack of intentionality or purposefulness. After all, you might hope for an ace when you draw a card, but you can’t choose one on purpose. You might call heads when you flip a coin, but you can’t know beforehand what the outcome will be. Thus the outcome is indeterminate, but is it purposeless? Not necessarily. Indeterminacy simply means the result cannot be predicted from the outset.

It should be noted that indeterminacy does not imply that God does not have foreknowledge of future events. Christians ought not to be uncomfortable with the idea of God interacting with his creation through chance. We often describe a seemingly-random (i.e. unplanned by us) sequence of events as being “providential,” or planned by God.

In biology, it is very hard or impossible to calculate precise probabilities for most processes, so when we say a process is random, we typically mean it is extremely unpredictable. Eventually we will discuss randomness within biological evolution, but first we must consider some simpler processes, like the self-assembly of a virus.

Viruses are remarkably efficient entities. Coiled tightly within a protein-based shell is a small amount of DNA needed for self-replication. The shell, called a capsid, is made of many repeating protein subunits and is therefore highly symmetrical (see figure). Important biomedical insights have certainly been gleaned from structural studies of viruses, but viruses also teach us about the emergence of order from non-order.

The virus life cycle has four main steps: 1) enter a host cell, 2) hijack the cell’s replication and translation machinery to make many copies of itself, 3) assemble into many virus particles, and 4) exit the cell to invade another host.

When I first learned about this process, I found it very hard to believe it just “happens.” The idea that a bunch of molecules bumping into each other inside a crowded cell could spontaneously assembly into a fully-functional virus seemed a bit far-fetched. Many viral capsids have over 100 protein subunits that must interact with each other in just the right way, or it won’t work. Surely there must be something driving this process, right?

There is! Random motion. I had to see it to believe it. I distinctly remember sitting in class during my first year of graduate school when the professor demonstrated self-assembly of a virus using a 3D model as shown in the following video. In less than 30 seconds, you can watch a jumbled heap of proteins become a beautifully ordered structure.

As the narrator explains, sub-assemblies form and break apart en route to the most stable structure, the full capsid. As the sub-assemblies begin to form, further associations with free subunits become more favorable and as a result occur rapidly, while the final steps may take considerably longer. While the subunits in the model are rigid, in reality the proteins take on multiple conformations, allowing the capsid to “breathe.”

Amazing as it is, the system we just considered—one virus capsid in a jar—is pretty simple. One wonders how self-assembly can happen in a crowded cell, where there are countless other molecules diffusing around, potentially getting in the way. We can’t directly see how it happens in a cell, but we can reconstitute the process in a test tube using different combinations of constituent molecules.

Consider two viruses, where each protein subunit in one virus is the mirror image of the corresponding subunit in the other. Putting the two viruses together by hand would be pretty tricky, because the constituent parts look so similar. But random motion can do the job in short order:

From this model, we can see clearly, in real-time, how distinct complex structures can arise from their parts randomly interacting with one another. Many large viruses also use special scaffolding proteins to assist in the assembly process, and some even use their own genomes as a scaffold. In addition, two closely-related viruses that happen to infect the same cell can exchange parts to create a new virus. This is one way viruses can evolve quickly to evade the host’s immune system.

Here we have seen how viruses demonstrate a principle inherent in God’s world—that order can emerge out of chaos from random processes. In my next post, we will look at some other biological processes that make use of—rather, depend on—randomness. This will set the stage for us to see that such processes can not only assemble a structure within seconds or minutes, but also generate complex, information-bearing molecules over billions of years. Even though the freedom inherent in nature sometimes produces unintelligently-designed structures (like viruses, which can kill us), we see that God has made, and continues to oversee by his providence, a good creation that, at least in part, is capable of creating itself.

Next weekend, we’ll continue this series about randomness and God’s divine will. Up next: how God created the body to heal itself, and how can random mutations can be both harmful and benign.

“This is 2,300 year old wisdom from the Book of Ecclesiastes that seems to very concisely understand the water cycle. That water evaporates from the ocean, gets stored in the atmosphere via clouds, comes down as snow or rain, and when it comes down on the mountain it’s often stored there, as snow is gathered via groundwater, streams, and rivers, and then through the river, returns to the ocean, again. What a beautiful, complex, interdependent, wonderfully mysterious way of providing water, life to the land … But what does this beautiful system teach us, Father, Son and Holy Spirit, about who we are? What is your word, God, about this river, that runs through the center of where we live?”

In this sermon, Pastor Jon Van Sloten of New Hope Church in Calgary, Alberta, describes how he set out to learn where the water from the Bow River, near their home in the Rocky Mountains, actually comes from. He interviewed scientists who study hydrology and have learned a curious truth about how this particular river keeps a steady flow the full year round. This modulating geophysical “safeguard,” which allows the Rocky Mountains to hold water and let it out at a slow trickle rather than a deluge during the annual snowmelt, speaks to Van Sloten of God’s grace at work in the world—grace we can’t see with the naked eye, but is there all the same.

Alice in Wonderland, by Lewis Caroll

Theology once held a seat of high regard among the sciences. During the Middle Ages theology was the Queen of the Sciences, and it sat enthroned at the core of academic studies throughout Europe. Many of the great European universities developed from the cathedral schools where theology was the nucleus around which all other study revolved and found its meaning.

The reason for this position of favor was that theology was discussion about – or the study of – God himself. In God, believers found their purpose and very existence. Therefore, God was not a position to be reasoned to; rather, reason flowed from one’s understanding of who God is and his relationship to humanity.

As Queen, theology’s function was not to discover all the answers herself but rather to encourage the other subjects – her subjects – to pursue truth. Math should discover that 2+2=4; biology should discover the mechanism of creation; psychology should discover the role of parent bonding in childhood development; but it was the role of the Queen to give meaning to the truths of her subjects.

In other words, 2+2=4 neither proves nor disproves the Creator, but theology – a profound belief in the Creator – sees the beauty in the ordered world around us. Theology and math are not the same. They answer different questions. But they are not completely separate answers; together they form a more complete answer to each of their individual questions. To quote Stephen Jay Gould, they are “nonoverlapping magesteria” to be certain, but they are also “interdigitating in wondrously complex ways along their joint border. Many of our deepest questions call upon aspects of both for different parts of a full answer” (Gould, “Nonoverlapping Magisteria,” Natural History 106 (March 1997).

It is unfortunate that Gould’s later explanation of these nonoverlapping magesteria left so little room for theology; in a sense, banishing the Queen almost completely to the hinterlands of the academic kingdom. The image of these nonoverlapping magesteria “interdigitating in wondrously complex ways,” however, is still worth considering. This image serves as a reminder that one should not reason from God or theological perspectives to mathematical principles or scientific theories anymore than one should reason from mathematical principles or scientific theories to the existence of God or the non-existence of God. In their “interdigitating,” however, in the beautiful harmonies between theology and the other sciences a fuller answer is given – an answer that provides not only facts but also meaning.

Unfortunately, the history of theology’s reign through the ages is questionable at best. The Queen far too often hampered instead of encouraged the pursuit of truth by her subjects. Today, many put the Queen at direct odds with her subjects, and this has led to a comical and tragic caricature of theology in our current society – a Queen who settles all difficulties, great or small, with the same solution, without bothering to look around, and by yelling, “Off with their heads.”

As Christians, who care deeply for the pursuit of truth, we cannot – and must not – attempt to restore theology to a place of prestige by destroying the work of her subjects or by belittling the work of those who practice them. We must not attempt to settle every difficulty between theology and the other sciences by calling for the heads of others to roll while we bury our own heads in the sand.

Rather, as theologians, whether professional or lay, we must assist theology to ascend to her throne as Queen of the Sciences by encouraging the pursuit of truth in all fields wherever they lead, by humbly entering into discussion with her subjects concerning the truth they discover, and by proclaiming the Truth that gives meaning to all truth – Jesus Christ, our Lord.

George Murphy notes that while the science and theology dialogue has grown considerably in the past 30 years, much of it remains at an academic level. While it provides an important foundation, that alone is not going to do the job that the church needs it to do—to come out in Christian education in parishes, in preaching, in pastoral care, in the social action of the church.

During his seminary education, Dr. Murphy also gained a deeper understanding of Luther’s theology of the cross, and he realized that it’s really the best way to approach the science and theology dialogue. The theology of the cross helps us deal not only with an issue like evolution, and but more generally with the whole question of how God acts in the world and how we know God.

Most science and theology dialogue is restricted to discussion of creation and origins. But at the core of the Gospel of is not simply the doctrine of creation—it’s salvation, it’s the work of Christ in saving humanity and in saving the whole creation.

Suppose a man falls among thieves, or wild beasts; is shipwrecked at sea by a sudden gale; is killed by a falling house or tree. Suppose another man wandering through the desert finds help in his straits; having been tossed by the waves, reaches harbor; miraculously escapes death by a finger’s breadth. Carnal reason ascribes all such happenings, whether prosperous or adverse, to fortune. But anyone who has been taught by Christ’s lips that all the hairs if his head are numbered [Matt. 10:30] will look further afield for a cause, and will consider that all events are governed by God’s secret plan.

In this passage, Calvin presents belief in “fortune” as evidence of carnal reasoning, and statements like this one have contributed to a widely-held notion that modern scientific understandings of the role that randomness plays in nature is inconsistent with belief in divine providence. In other words, if “randomness” equals blind and capricious “fortune,” then how can God be said to be working all things to his ends?

But Calvin could not have known of the very different understanding of randomness held by today’s scholars. Physical scientists, mathematicians, and statisticians have not yet agreed on a single unambiguous definition of the term “randomness,” but among these scientists, the term consistently refers to a family of related concepts focusing on unpredictability of the outcomes of single events and the absence of pattern in sequences of outcomes. I like this statement by John Polkinghorne, “Chance doesn't mean meaningless randomness, but historical contingency. This happens rather than that, and that's the way that novelty, new things, come about.” In Polkinghorne’s view, chance is an agent of creativity and can be perceived as being purposeful.

In fact, there are abundant examples of phenomena in nature in which randomness plays a role one could understand as being purposeful. For example, osmosis is a marvelous mechanism that enables all 10 trillion cells in our bodies to be nourished – it depends on the random motion of molecules. The human immune system is able to defend the body against attacks from millions of different microorganisms using a relatively small number of building blocks and random combinations of these to fashion defenses specific to each adversary. We never take a breath and find it to be all nitrogen or carbon dioxide – random motion of molecules keeps oxygen close to uniformly distributed throughout the atmosphere.

In 2007, a British statistician, David Bartholomew published God, Chance, and Purpose in which he argues that God “can have it both ways”—that he can use low level randomness to accomplish divine purposes while simultaneously maintaining order at a higher level. Of course, we cannot prove that God ordained these random processes to achieve divine purposes in the world. But to a person of faith, such an interpretation in both consistent with the observations we make in science and with the Scriptural notion of God’s providential care for the world.

Considerations like these led the John Templeton Foundation to provide a generous grant of $1.69 million to support a new research initiative on the theme of Randomness and Divine providence. Beginning this past summer, the program has the purpose of providing support for solid theoretical exploration of the kinds of ideas and possibilities expressed above—involving theology, philosophy, natural science, mathematics, and statistics. The grant will support individual scholars and teams of scholars who are willing to devote a significant amount of time between March of 2013 and June of 2015 to such work, and the project’s request for proposals suggests the following as questions researchers might pursue:

• How might God work providentially through indeterminate processes? Can recent advances in understanding the nature of randomness offered by algorithmic information theory, physics, biology, and other sciences provide insight into this question?
• Can we bring clarity to the concept of "randomness"? Philosophers and scientists have tried on occasion to give precise definitions of when a process is random, but more work needs to be done on the question. How do (or should) conceptions of randomness vary across academic disciplines?
• What are some possible implications of randomness for hiding or unfolding divine creativity and purpose in the world? Could God use randomness to (1) generate creativity, (2) hide divine actions, or (3) unfold information? Why might God do so?
• How might we identify and come to understand a significant collection of nondeterministic processes in which agents could intentionally employ randomness to bring about purposeful results?
• How might we mathematically and physically model random processes in ways that help us understand how divine providence could be exercised in a "chance-governed" world?
• How do "laws and orders" in nature interplay with "chance and randomness" in bringing about results that can be interpreted as aspects of divine providence?
• Might randomness be evidence of limitations in human knowledge but nothing more? Or might it be evidence of ontological indeterminism? Might this be tested?
• What implications does randomness have for aspects of God’s relationship with the physical world such as God’s relationship to time and God’s role in causation? How might randomness be reconciled with God’s foreknowledge?
• How might an understanding of providence based on an extended Molinism and/or open theology incorporate randomness? For example, could an extended Molinism provide a plausible account of the relationship between quantum mechanics and divine providence?
• What are some theodical implications of randomness, particularly for the issue of natural evil?
• How have the theological traditions of Augustine, Maimonides, Aquinas, Luther, and Calvin addressed chance and fortune? In what ways might they incorporate ontological randomness?
• How do or could religions other than the Judeo/Christian tradition understand and incorporate randomness?
• How is the concept of randomness understood by advocates of secularism, naturalism, and new atheism? What are the strengths and weaknesses of these usages?
• How might an understanding of randomness in the world alter our conceptions of divinity, especially our understanding of divine providence?

Despite the range of issues mentioned above, research is by no means restricted only to these topics. In fact, the structure of the program is designed to foster collaboration and build community between scholars, with the end of expanding the range and integration of their work: two conferences will be held to bring scholars together with each other and then with members of the public—one at Calvin College in 2013 and the other at Fuller Theological Seminary in 2015. To get more information and to learn how to submit a proposal, see the project website; then join us in exploring the truth that all creation glorifies God—even randomness!

Is it possible to fully understand and practice Scripture without connecting with science? If science reveals God’s attributes, how can we fully relate to Him without some ongoing reference to the information revealed in scientific inquiry? Even more specifically, as preaching pastors, how many are we excluding if we ignore important facets of our congregations’ worldviews?

Now in a collaborative environment like this, it is easy to stay on an intellectual level. But we are pastors who are practitioners, so let me speak personally to get the discussion into the realm of the church world and what may or may not work for you. Some 27 years ago, while exploring whether or not to go to pastor Northland Church, I sensed I’d found kindred spirits when reading in its philosophy of ministry:

People are not just to be understood as sinners but as beings greatly affected by the bodies and physical world they inhabit.

How then would I best address that physical world in the context of understanding its value to our spiritual formation?

Different Approaches to Scripture and Science

Since the sermon is the main component used to build the congregation’s collective approach to understanding how the church relates to the world, I want to take a few moments to lay out what has worked in my preaching and what has not when it comes to science and more specifically the subject of evolution:

1. I decided on a hermeneutical approach. How would God’s patterns in creation published in scientific findings inform my understanding of Scripture?

• I would not use the “Science and Faith are in conflict” (J.W. Draper/A.D. White¹) approach, since I am neither a fundamentalist nor someone whom would wish to violate the spirit of those who penned Scripture who understood God to be over all the world, both hill and Temple (Psalm 24:1-10).
• I would not use S.J. Gould’s² “Non-Overlapping Magisteria” approach, which “ghettoizes” both science and faith. To say one only answers “how” and the other only answers “why” is to miss the richness of both.
• I would not use Pierre Teilhard de Chardin’s³ or Ian Barbour’s³ “Integration / Unity” approach, since such an approach requires extensive knowledge of both science and theology and almost inevitably leads to process theology.
• I would use the “Dialogue” (W.G. Pollard⁵) approach, since it emphasizes insight and investigation rather than answers, thereby leading to a sense of wonder and worship. Such an approach minimizes the hubris of knowledge (that will almost certainly pass away) and the hostility toward different perspectives.

2. I decided on a related-referential model rather than an issue-oriented one.

• Any model chosen must fit the personal style of the preacher or it will become uncomfortable and soon unused. I am more the Columbo/sloppy trench coat, “Oh that reminds me…one more thing…” investigator rather than a “light bulb hanging over the head breaking down your resistance” kind of confronter. So I use science as “now what do you make of that?” kind of illustration rather than an argument for my perspective.
• The model must also fit the personality of the church. In our church issue-oriented subjects must be taught in classes or small groups where people have the chance to question/comment in ways not usually done in response to sermons.

3. Our church has decided that being a witness of the incarnate Christ means engaging, and learning from, the world as it is presently.

• Following God’s example in Christ is entering into the world and serving in all its realms: spiritual, emotional, physical, and social.
• Christ used the common knowledge people already had (much of it from nature) to reveal God.

Recognizing Cultural Perspectives

Having laid out what seems like a tidy approach, I will now recognize the difficulties I have experienced, as a pastor, pertaining to evolution, for understandable but remediable reasons. The church has a particular culture that prevents fully engaging science.

1. Most in a congregation do not decouple or differentiate the belief in a philosophy of random and purposeless evolution from the instances of incremental improvements that may point ultimately to an Organizing Principal.
2. Most have not been taught the literary genre distinctions between the writings of Genesis 1 and a science textbook.
3. Most have not considered the possibility that Adam and Eve may not have been uniquely and separately physically created for their sole role in the beginning of human kind. They need alternatives involving figures that do not contradict the point of the narrative.
4. Most have not considered the complementary nature of the Biblical narrative of redemption out of death and the evolutionary one.

To be sure, when a pastor addresses the alternatives, or even makes an explanatory reference using evolution, that pastor can expect a variation of this conversation I had with a parishioner (who walked out during a sermon) a little over a year ago:

____________, I know I upset you with the reference I made to evolution. You have been listening to my teaching for many years. I hope you know by now how the high view of Scripture as the final source of truth and authority I hold and this church holds. 'Well, I thought I did but now I am not so sure,' answered this lady who has been trying to get Ken Hamm to our church for some years. You know I would never do anything to lessen the importance of Scripture. 'Pastor, when you confess evolution, you not only make a liar out of Scripture, you become the reason young people are not following God and are living lives without regard to the Bible, and are in some cases committing suicide.'

This woman is not an unintelligent person. She is a professional nurse and is leading in a mission organization. She was just scared. Happily, she is still in the church and has decided after some more reflection that maybe I do not want to lead young people into orgies and death after all.

Summary Thoughts

In 1632 Galileo warned his fellow believers of a trap they were walking into by resisting the conclusions of a scientific investigation:

Take note, theologians, that in your desire to make matters of faith out of propositions relating to the fixity of sun and earth you run the risk of eventually having to condemn as heretics those who would declare the earth to stand still and the sun to change position--eventually, I say, at such a time as it might be physically or logically proved that the earth moves and the sun stands still.⁶

We would do well to be the church learning God’s truth as discovered by scientists, not resisting its discomfort or its perceived threat to our traditional interpretations of Scripture.

We worship a God of history, and references to our physical world fit well, given some time, into our metaphysical journey. One only has to look at the Old and New Testaments to see how central the elements of creation are to understanding the activity, and thus the “nature” of God. The references are not simply meant to be objective facts; they are to open the door to vistas beyond. If postmodernism has made us aware of the illusion of pure objectivity, then it has also taught us something of the value of pre-modernism, where the lines between the physical and spiritual are connecting points.

Of course nature is not prescriptive, nor does it present comprehensive pictures of God’s personality. One of the most intellectually capable scientists I know does not believe in God because of his observations of ants organizing slave colonies. It offends his sense of egalitarianism. Talk about making a mountain out of an anthill! Theologizing from particular scientific observations is hyper-interpretive.

Yet, as all creation was made by and for Him (Colossians 1:16-17), when it comes to the insights that may be offered by scientific information (especially evolution) it is difficult for those who have been given a modicum of faith not to see the possibility of:

• An Organizing Principle
• An Orchestrated Similarity among the physical, personal, social, and spiritual realms
• An increased ability and likelihood to respond to the outside world in ways that benefit all
• Redeeming relationships involving sacrifice, not all of which are initially positive or intentional (Romans 8:28)
• Problematic instances that would seem to negate the idea of a loving kind Creator may be a part of a more positive trend.
• Greater confidence, as a result of faith, in uncontrollable circumstances being used for good eventually

My goal as a pastor is to equip the saints in my sphere of influence to see Christ and to worship Him. If those in my influence only can see God in Scripture, then they are half blind. But if we together can help each other see the unfolding redemptive purposes of every realm - of scientific inquiry, of business practice, of artistic expression, of church/family support for every individual in every field of endeavor – then we will be not only 20-20 but 3-D in every direction!

Of course, such a result will require a more comprehensive approach in preaching. And such comprehension will require a continuing dialogue with those who can help us see the truth from different perspectives.

In my previous essay, I discussed “Darwin’s finches” and how surprisingly little Charles Darwin himself had to say about them. In fact, it was actually the British ornithologist David Lack (1910-1973) who conducted the critical research that immortalized the finches in biology textbooks and popular lore. In 1973, the eminent German zoologist Ernst Mayr wrote:

Already well known among professional ornithologists, his work on the Galapagos finches gave David Lack world fame… There is no modern textbook of zoology, evolution or ecology which does not include an account of his work.¹

Ernst W. Mayr

Decades have passed since Mayr wrote these words, and David Lack’s name has largely faded from public discourse. On the other hand, the Galapagos finches have become one of the most recognized symbols of evolution in the world today. Does it really matter whether Lack or Darwin gets credit for describing the evolution of these remarkable birds?

Insofar as evolutionary theory contrasted with religious belief, it makes a big difference. In a culture that is eager to equate evolution with atheism, it should come as no surprise that these birds are only known as “Darwin’s finches”. Darwin’s personal struggles and ultimate rejection of Christianity are well documented, and people are eager to link his loss of faith to his evolutionary theory. David Lack, on the other hand, began his scientific career as an agnostic, but shortly after publishing his famous book on the evolution of Galápagos finches, he converted to Christianity! ²

A Christian at the forefront of evolutionary biology

Lack’s Christian conversion did not mark the end of his scientific achievements, either. In fact, he continued as a prolific researcher until just weeks before he died. Among his many achievements, he was Director of the Edward Grey Institute of Field Ornithology (1945-1973), Fellow of the Royal Society, and President of both the International Ornithological Congress (1962-66) and the British Ecological Society (1964-65). His fellow scientists held him in great esteem:

He was described as one of the most outstanding among world ornithologists; he was certainly this, but he was also one of the world’s leading evolutionists. All the time one saw developing his use of birds as material for the study of wider, deeper, biological problems.³

David Lack at the International Ornithological Congress, 1962.

Clearly David Lack was an outstanding scientist, and his commitment to Christianity did not tarnish, hinder, or undermine his research on evolution. But we might also ask, what was Lack like as a Christian? Did he keep his faith hidden from view, afraid that it might compromise his reputation as a scientist? Ernst Mayr, who interacted with David Lack professionally and personally for nearly 40 years, had this to say:

I have known only few people with such deep moral convictions as David Lack. He applied very high standards to his own work and was not inclined to condone shoddiness, superficiality and lack of sincerity in others. This did not always go well with those who preferred to compromise in favour of temporary expediency. David had been raised in an environment in which great stress was layed on moral principles and this attitude was later reinforced by his Christian faith. This explains his extraordinary unselfishness and modesty, and his great devotion to his family, to his students, to his friends, and to all the things that he lived for. The equanimity, indeed serenity, with which he faced death after his terminal cancer had been diagnosed is further evidence of the strength which his faith gave him.⁴

Like Asa Gray⁵ before him, and Francis Collins⁶ after, David Lack was an sincere, devout Christian, as well as a leading scientist who employed evolutionary theory to make brilliant discoveries about the natural world. Though Lack did not see any conflict between his scientific and Christian beliefs, he was sympathetic to the concerns of his fellow Christians. Therefore, ten years after publishing his masterpiece on Darwin’s Finches, Lack wrote another book entitled Evolutionary Theory and Christian Belief: The Unresolved Conflict.

Originally published in 1957, this book deals with the very same science and faith questions that Christians struggle with today— topics like randomness and chance, death in nature, miracles, and evolutionary ethics. While it would be unreasonable to expect anyone to completely resolve these matters, Lack offered numerous insights both as a devout Christian and one of the world’s leading biologists.

Let’s take a brief look at how Lack addressed some of these questions.

Blind Chance or Divine Plan?

Evolutionary theory does not invoke supernatural forces in explaining the history of life on Earth; instead, it relies on naturally-occurring processes to account for the vast diversity of life. Additionally, it explains animal behavior largely in terms of survival and reproduction, without appealing to any higher purpose of life. Taken together, does this imply that God is absent, and that our lives are ultimately meaningless?

David Lack responded,

Behind the criticism that Darwinism means that evolution is either random or rigidly determined lies the fear that evolution proceeds blindly, and not in accordance with a divine plan. This is another problem that really lies outside the terms of reference of biology. It is true that biologists have inferred that, because evolution occurs by natural selection, there is no divine plan; but they are being as illogical as those theologians whom they rightly criticize for inferring that, because there is a divine plan, evolution cannot be the result of natural selection.⁷

When rendering judgment on the ultimate meaning of life, biologists are speaking from their person beliefs, not from scientific authority. Moreover, Lack pointed out that many science enthusiasts have employed the concept of “randomness” in ambiguous and misleading ways:

Mutations are random in relation to the needs of the animal, but natural selection is not. Selection, as the word implies, is the reverse of chance.⁸

In support of his view, Lack pointed out that convergent evolution has produced uncanny resemblances between distantly-related species across the world, notably among marsupials in Australia. Different evolutionary trajectories can lead to very similar results.⁹

Death in Nature

After addressing concerns about the seeming “randomness” of evolution, Lack turned to another great concern, the role of death in natural selection:

Various writers–some Christian and others agnostic–have been troubled about natural selection not only because it seems too random, but also because it is so unpleasant.¹⁰

Genetic mutations are generally harmful, and for evolution by natural selection to produce new forms of life, an awful lot of organisms must die. For many Christians, it is inconceivable that a loving and merciful God would allow death on such a vast scale.

But Lack also pointed out that rejecting evolutionary theory doesn’t actually get rid of the problem of death. Regardless of what we think about evolution, the brute fact of mass extinction remains. Fossils of innumerable animals, plants, and microorganisms clearly demonstrate that the vast majority of species that have ever lived are now dead. It may be quite troubling for us to observe that our planet is a giant graveyard of natural history, but rejecting evolution will not change this fact.

Some Christians conclude that death could not have been part of the divine plan; instead, it must be the work of the devil, or the result of human sin. But this interpretation contains an implicit assumption that death is always evil. Is this really true? David Lack offered two intriguing insights:

courtship, seen in Basai, Gurgaon, India.

1. For a population to maintain a stable size, all births must be balanced by a corresponding number of deaths. A world in which no animals die is a world in which no animals are born. That means no reproduction, no courtship, and by implication, no singing birds—much to the dismay of ornithologists and people in love!

2. Some people, taking cues from Isaiah 11:6-7, suppose that in a perfect world, animals only eat plants. But in fact, plants themselves depend on the bacterial decay of dead organisms. If animals didn't die, then essential nutrients would disappear from the ground, and plants could not continue to grow. Eventually, there would be nothing left for animals to eat, and all life would cease.¹¹

Miracles

Many Christians are uncomfortable with evolutionary theory because it denies a miraculous, supernatural origin of life. They fear that if those miracles are denied, it might lead people to reject the possibility of miracles altogether, including the central feature of the Christian faith—the resurrection of Jesus from the dead.

As a devout Christian, David Lack certainly affirmed the fundamental tenets of the gospel. But at the same time, he explained to his readers that invoking miracles to account for unusual features of the natural world is not particularly helpful when trying to deepen our understanding of God’s great multitude of creatures:

[The biologist's] research depends on repeated observations. It need not, as popularly supposed, consist solely, or even mainly of measurements and experiments, but unless events are repeated, they cannot be assessed by science. Hence truly unique events come outside the domain of science, though biologists are not usually convinced when told they must, therefore, leave such problems as miracles to others. For one of the chief ways in which research has advanced is through the discovery of apparent exceptions to the known rules, and if further study shows the exceptions to be replicable, new regularities are revealed from which modified rules can be propounded. This method has been so successful that the biologist tends to doubt whether there are any types of irregularity, or seeming irregularity, that will not yield to it.¹²

But just because a scientist cannot repeat a particular event doesn’t mean it didn’t happen. Both natural history and human history contain unique events that only happened once. As we peer into the past, the difficulty of discerning fact from fiction inspires us to further investigate the mysteries that surround us.

Conclusion

David Lack’s book Evolutionary Theory and Christian Belief was quite insightful, but his enduring achievements took place in evolutionary biology, a place where many Christians are afraid to tread. While it is significant that he himself found no contradiction between his faith and his science, perhaps the greatest testament to the compatibility between Christian faith and evolution is the life he led as a believer in both. As we saw in Ernst Mayr’s candid praise, Lack reflected the light of Christ through both his personal and his professional relationships.

Today, many voices in our culture still insist that evolution is incompatible with a sincere faith in Jesus, but a careful look at history demonstrates otherwise. In the future, perhaps more people of faith will have confidence to study biology knowing that one of the most iconic symbols of evolution—the Galapagos finches—owe their fame in large part to a devout Christian named David Lack.

Author's Note

I am so thankful that I grew up in a Christian environment, which both kindled and nurtured my relationship with Jesus Christ. The Biblical instruction I received from my parents, pastors, and teachers has been invaluable as I walk out my love for the Lord from day to day. However, there was one specific topic growing up which was not fully addressed, namely evolutionary theory.

Coming from a conservative Christian background, evolution was given little or no thought because of its seeming contradiction to the creation story in Genesis. To me, evolution meant a monkey became a human, and as far as I knew, I had never seen that happen! So, of course, it appeared too improbable to hold any truth. When it was discussed, an inadequate picture of its ideas was often painted, which caused immediate suspicion and rejection of the theory. I don’t think this was intentional, but most Christians have never learned an unbiased, in-depth theory of evolution that is completely detached from societal agendas and philosophical conclusions. Therefore, their explanations of the theory are often misinformed.

My senior year of high school, I took AP Biology, and finally learned the scientific reasoning supporting this theory. I was surprised by how logical and obvious the mechanisms of change (such as mutations, natural selection, genetic drift, and so on) were that gave rise to new species. My subsequent response was, “No wonder people believe evolution occurred.” At that point, I was convinced that microevolution (evolution within a species) existed, but I was still questioning macroevolution.

Now, being at Point Loma Nazarene University as an undergrad in the Biology-Chemistry major and a year-round, student intern at BioLogos, my understanding of evolution has expanded enormously. I have enjoyed critically thinking through the evidence for evolution and reading articles that tackle difficult issues at the interface of science and Christian faith. Ultimately, I know that God has created all things, but the processes he used surpass my small understanding.

My personal wrestling with evolution and quest for truth has led to times of prayer and studying God’s Word, which has deepened my love for him in ways I cannot express. The first chapters of Genesis, in particular, have come alive. My whole life, the creation story was a straightforward list of facts about the creation of the world; I never searched further. I didn’t even perceive the truths Genesis declared over my very identity and God’s character. The more I study his Word and handiwork, I glimpse the awesomeness and majesty of the Creator, who loves me much more than I know. There is still so much to learn, but I am confident that he will lead me into all truth as I seek him out.

I desire to give others the opportunity to see evolution accurately and to distinguish it from the traditional, philosophical, and personal conclusions that too often cloud the scientific theory. I believe these conclusions alienate Christians from evolution more than the scientific theory itself. Ultimately, I do not mean to convince someone about evolution, but simply to give them the freedom to understand it.

Therefore, my goal for this podcast is two-fold:

• First, to offer a new perspective on randomness within natural processes that removes its negative connotations (especially as it relates to evolution).
• Second, to expose why evolution is powerless to support conclusions beyond the physical realm.

This will hopefully encourage others to study evolutionary theory and draw their own conclusions about its meaning in the framework of their faith.

Many of the games I enjoyed playing involve a combination of strategy and randomness: card games of various sorts, backgammon, and board games like Monopoly and Parcheesi. Some games that rely exclusively on chance (like War and Candy Land) or too heavily on chance (like Sorry) quickly became uninteresting to me. In fact, for Sorry, War, and several other games, I introduced additional rules to change the balance of strategy and luck—for example, by allowing each player to hold a hand of cards rather than merely flip a card and follow its bidding.

When my children were young, I played many games with them, especially those involving some amount of chance. I always play to win, so games of pure strategy like chess gave me too great an advantage—at least when they were still young. I still remember the first time I played the German game Mitternachtspartie with my children and some of their cousins. The game uses a die on which the number 5 has been replaced with the image of Hugo the ghost. Each player rolls the die and moves one of his figures the specified number of squares, unless Hugo is rolled, in which case Hugo moves instead.

I quickly worked out the expected distance Hugo would move for each of my turns and the expected number of squares I would get to move my own figures each turn. Using that information, I could strategically place my figures in the opening portion of the game. I fully expected to win this first game, since my young children were going to have to learn from experience what I already knew by the mathematics of probability. I lost—badly. As it turned out, the die had two Hugos on it. So compared to my expectations, Hugo moved twice as often, and my figures moved slightly less far. That combination turned the carefully calculated positioning of my figures into a disaster.

From Fun and Games to Science

I still enjoy playing games, including games that involve chance. But these days I encounter randomness even more often in my profession. I was trained as a mathematician and now work at the intersection of mathematics, statistics, and computer science. Like many scientists, I use randomness on a daily basis as part of our toolkit for modeling and investigating all sorts of phenomena. Models known as stochastic models, which explicitly incorporate random components, often via simulation in computer software, are used to model everything from diffusion to genetics to quantum mechanics. Insurance companies and financial institutions use stochastic models to manage risk. If we include all the applications of statistics, then almost no area of science is untouched by the use of randomness.

Most of the time, scientists and game players alike don’t devote much thought to just what makes randomness tick. But they both know that the better they understand the probabilities, the more successful they are. Nevertheless, if you ask many of them what it means for something to be random, they may struggle to put it into words. I won’t try to give a precise definition either, but it is important that we have some idea what we are talking about, so let’s consider one of the prototypical examples of randomness: the tossing of a fair coin.

If I flip a coin, the result could be heads or tails. Until I flip the coin, I don’t know which it will be. In this sense, the coin toss is unpredictable. If the coin is fair, each result is equally likely, so while I cannot say in advance whether a particular result will be heads or tails, I can say something about a large number of flips: approximately half should be heads and the other half tails.

A little mathematics even allows me to determine a range around 50% in which the percentage will almost surely lie. For example, if I flip a fair coin 1,000 times, the percentage of heads will most likely be between 45% and 55% (where “most likely” means a 99% chance). If the percentage of heads lies outside this range—especially if it is quite far outside this range—I am going to be suspicious that the coin flipping process is not fair. That’s one of the key ideas in statistics: not only can we calculate the frequency with which an event occurs, but we can compare data to a stochastic model to see if they are compatible or incompatible.

There are several interesting things we can learn by considering a coin toss. First, probability calculations rely on assumptions. If the assumptions are incorrect, then the probability calculations will also be incorrect. For example, if the coin is biased (such as one that is heads 60% of the time), but we assume it is fair, then the probability calculations given above will be wrong. Of course, if the assumptions are not too far from correct, the results may still be sufficiently accurate for scientific conclusions. If we have an appropriate way to collect data, then we can test our assumptions by comparing data to projections made based on the assumptions.

Second, “random” does not imply “equally likely.” A fair coin should have equal probabilities of heads or tails, but a biased coin is no less random. It’s just different. It is not as simple to handle arithmetically as a situation in which all outcomes are equally likely, but it is not otherwise special. It is a common mistake to assume random events are equally likely when they are not (or when that assumption is not justified).

Third, randomness is about the process. It is a fun experiment to flip a penny 100 times, then spin a penny 100 times and record the side that is showing when it finally tips over, then to stand the penny on end (this takes a steady hand and a little practice) and record which side is showing after pounding the table. These are three different processes, and they do not yield the same results.

Fourth, random processes produce patterns. I sometimes ask my students to mentally flip a coin and record the results as a sequence of letters (e.g., “HTTHHTHT”). Then I have them actually flip a coin and record the results. If the sequences are long enough, I can almost always tell them which is which. The sequences imagined by the students tend to have too few runs of consecutive heads or tails. The sequences based on real coin flips usually include several heads in a row. People not familiar with randomness are often surprised at the patterns that result and assume that the process must not have been random when they perceive a pattern. Our eyes and minds are drawn to similarities and patterns—even those that are produced purely randomly. This can lead us to draw false conclusions from coincidences of all sorts.

Consider the image in Figure 1. It was constructed using a computer to randomly throw 300 darts at a square board. Every position on the board was equally likely to be hit by a dart. This does not, however, mean that the dots are evenly spaced. There are 100 smaller squares. The average is three dots per square. But your eye is likely drawn to some clusters and voids. My eye also catches a graceful downward swoop in the lower part of the upper left quarter. All of this is exactly what we should expect from this random process. If we repeated this experiment, we should expect similar results. Several of the smaller squares would be empty and some others would have two or three times the average number of dots, but these clusters and voids would appear in different places.

Finally, randomness can be used to produce patterns intentionally. Consider the two pictures in Figure 2. You may think the two pictures are identical, but they are not. However, they were each constructed using the same random process:

1. Start at the lower left corner of the big triangle.
2. Randomly choose one of the three corners of the big triangle.
3. Move half way to that corner, placing a dot at the new location.
4. Repeat steps 2 and 3, 50,000 times.

The first few steps of this process for each image are illustrated in Figure 3. Although the final images look very similar, the route taken to get there is very different. In fact, the only point the two images have in common is the starting point. As the creator of the program that generated these images, I knew full well that the result would resemble a fractal image known to mathematicians as Sierpinski’s Triangle, even though I did not know or exercise any control over how the individual points would be selected.

Despite our familiarity with children’s games and the importance of stochastic models throughout the sciences, many Christians have a reaction to randomness that falls somewhere between uneasy and antagonistic. And yet, those same Christians may well watch the evening news to learn about public opinion polls forecasting upcoming elections, take prescription drugs approved by the FDA based on statistics found in clinical trials, obtain electrical power from a nuclear power plant that uses random fission reactions, and insure their cars with companies that rely on stochastic models to set the rates. The foundation of each of these activities is a thorough understanding of randomness that begins with the simple description above.

So where does the uneasiness come from? Likely it comes from the feeling that taking randomness seriously means not taking God seriously. Or put more strongly, it comes from a fear that believing in randomness means not believing in God. Next week we’ll address that problem by asking the question, “Could God use randomness to achieve his purposes?”

In the 1950s, Cage began using various methods of “casting lots” to determine how elements of his music would be chosen and arranged—principally the Chinese system of I Ching. His controversial program was to distance himself from his own creative process, and he explored many additional strategies to transform the role of “creator” into one of “observer.” Most famous of these was his musical composition, “4.33,” which consisted of a pianist sitting at the instrument doing nothing at all for four minutes and thirty-three seconds, while musician and audience listened to the ambient sounds of the concert hall. Yet contrary to that main thrust of Cage’s work, a description of the activities during the week-long residency at the Mountain Lake Workshop where the New River Watercolor Series were made suggests that choice, constraint, and intention were integral and inescapable tools in putting randomness to work for creative ends.

Here’s art historian and theorist Howard Risatti’s description of Cage’s plan of action for the New River Watercolors, from the website of artist Ray Kass, who runs the Mountain Lake program and was Cage’s collaborator for his work there:

Following upon [a previous (1983) Mountain Lake workshop] “painting experiment,” stones collected from the New River were sorted into three groups according to size, which were separately numbered; numerous and varied brushes were divided into two separately numbered groups; likewise, feathers to paint with, colors and washes, and papers were also divided and numbered. In this way, chance procedures using pages of random numbers that were now generated by a computer program could be used to determine the specific materials utilized for each painting (e.g., which painting instruments, what type of paper and which colors, how many washes, which stones to paint around, where to locate the stones on the paper).

While this list enumerates all the specific variables that Cage and his team submitted to chance, there was an incredible level of personal engagement with the materials: Cage didn’t just show us drawings of where the I Ching said the rocks ought to be, he (or his assistants) placed them on the paper and used them as guides to paint around. Large custom brushes were constructed to lay on washes of color, and even the paints were hand mixed, combined, and diluted according to his desires.

Cage’s use of chance, then, was not a “hands off” process, but neither was it a matter of total control: Cage selected processes to create a space of play between himself and the materials he used: the feather between himself and the paper, for instance, introduced variability of resistance and spring, its ability to hold paint, the width of the line. All of these things were elements of material ‘freedom,’ areas in which Cage asked the stuff he used to make the paintings to take part in the process—to contribute its own identity to the intentional, purposeful, and determined work of creating “based on chance.” This should not be surprising, as all art, all creation that we can observe, happens as a dialectic between materials and the creator, and such engagement and interaction in no way lessons the purpose of making, the end in sight.

Kass’ book The Sight of Silence: John Cage’s Complete Watercolors, gives a much more complete account of the tools, processes, and interpersonal reactions between Cage, Kass, and the team of student assistants who helped at almost every stage of the creation of the works. The book goes to great length to honor Cage’s ideal of being present in but not controlling the outcomes (not least by nearly always putting words like “choice” in quotation marks), but the description of his process makes the centrality of Cage’s personal aesthetic and artistic motives inescapable, even more than his physical engagement. What comes through perhaps even more than the way Cage intended to allow chance to ‘guide the creative process’ is that way Cage, himself, not only set the parameters of the chance he allowed into the system, not only engaged directly with the materials during the process, but also exercised judgment over the results, both in process and at the end:

“Cage decided he didn’t want the images of the stones to overlap or go off the sides of the paper. To guarantee this restriction, he created conditions and rules to limit their possible placements.” (p. 51)

“For this single painting [Series IV, #1, pictured above] Cage chose to confine the images of the rocks to a lower area of the paper that represented the proportion of the “golden rectangle. . .” (p. 57)

“While “choice” established much of the work’s nature, “chance” highlighted the intrinsic nature of the materials to reveal a refreshing presence.” (p. 59)

“[H]e initially decided to remove [the first painting of Series III] from the group, and then, liking it more, changed his mind and returned it to the group that would be signed.” (p. 56)

This last note is particularly interesting in that it highlights the fact that Cage was claiming these paintings, naming himself as their author, and was attentive to which ones he approved of enough to call his own. There is no way around the fact that Cage was subjectively as well as objectively the maker of these works: the author of the procedures by which they came to be, but well as the judge (and sometimes redeemer) of the results. For Cage, randomness was a tool, no different than the brushes or rocks or paints is that its specific parameters were chosen at the outset, and always used within the context of his over-arching vision. Perhaps we may likewise think of God’s use of chance—constrained by and tuned to the material conditions he established at the birth of the cosmos—as a way to both engage with and allow freedom for the creation itself.

With any work of art it is reasonable to ask, “Is it beautiful?” or more tellingly, “Would I hang this on my wall?” Seeing Cage’s watercolors for first time without any knowledge of the process or the relative fame of Cage himself, some might be intrigued by the structure of the work (the proportions of the golden rectangle, the overlapping stone shapes, the colors of the paint) while others would be completely uninterested, perhaps even after hearing about how they were made and seeing them in the context of the rest of the New River Watercolor series. But if you had been there in the shop as an assistant, or even observer, if you had been party to the relationships that developed even over the few days Cage spent at the Mountain Lake Workshop, your sense of the beauty of these paintings (and perhaps even scraps of paper Cage used to try out brushes or washes), would take on a different meaning, in much the way we treasure the crayon drawings of our children not because they are spectacular art, but because they are tokens of our relationship.

I make that observation to emphasize one other aspect of Cage’s creative process: that Cage was the instigator first and foremost of relationships of creation. His process created not only paintings but the fellowship that developed as the work was being done. That social, interpersonal dimension is what gives the objects a depth of meaning beyond their material composition, and suggests the particular roles humanity has been given by God. One role is to join into the creative process as lesser, but not unimportant co-creators with him; the other is to observe, recognize and celebrate his activity in the world. Where some will see randomness as evidence of an absent God, our knowledge of this most personal and participatory aspect of creation points us to the God who is with us.

With God’s creation as with human art, we may (or may not) marvel at any one particular “work,” or even think the specifics of how it was made are interesting or attractive; but knowledge of and fellowship with the artist transforms our appreciation of the process as well as its results. When we know the maker, we come to recognize and treasure even the most “random” bits of his handiwork, and name them as his, nonetheless.

As a pastor and evangelist, Keller takes these concerns seriously and offers suggestions for addressing them without requiring believers to adopt a particular view or accept a definitive answer. The six-part series that begins today is taken from a paper Dr. Keller presented at the first BioLogos Theology of Celebration Workshop in October of 2009. It considers three main clusters of questions lay people raise with their pastors when introduced to the teaching that biological evolution and biblical orthodoxy can be compatible. As a pastor and evangelist himself, Keller takes these concerns seriously and offers suggestions for addressing them without requiring believers adopt a particular view or accept a definitive answer. In this first installment, Keller gives an overview of the tension between biblical and scientific accounts on origins, before addressing the specific issues and responses in subsequent posts.

What's the Problem?

Many secular and many evangelical voices agree on one ‘truism’—that if you are an orthodox Christian with a high view of the authority of the Bible, you cannot believe in evolution in any form at all. New Atheist authors such as Richard Dawkins and creationist writers such as Ken Ham seem to have arrived at consensus on this, and so more and more in the general population are treating it as given. If you believe in God, you can’t believe in evolution. If you believe in evolution, you can’t believe in God.

This creates a problem for both doubters and believers. Many believers in western culture see the medical and technological advances achieved through science and are grateful for them. They have a very positive view of science. How then, can they reconcile what science seems to tell them about evolution with their traditional theological beliefs? Seekers and inquirers about Christianity can be even more perplexed. They may be drawn to many things about the Christian faith, but, they say, “I don’t see how I can believe the Bible if that means I have to reject science.”

However, there are many who question the premise that science and faith are irreconcilable. Many believe that a high view of the Bible does not demand belief in just one account of origins. They argue that we do not have to choose between an anti-science religion or an anti-religious science.¹ They think that there are a variety of ways in which God could have brought about the creation of life forms and human life using evolutionary processes, and that the picture of incompatibility between orthodox faith and evolutionary biology is greatly overdrawn.²

For example, there have been a number of efforts to argue that there may be evolutionary reasons for religious belief. That is, it may be that capacity for religious belief is ‘adaptive’ or is connected to other adaptive traits, passed down from our ancestors because they supported survival and reproduction. There is no consensus about this among evolutionary biologists. Nevertheless, its very proposal seems to be completely antithetical to any belief that God is objectively real. However, Christian philosopher Peter van Inwagen asks:

Suppose that God exists and wants supernaturalistic belief to be a human universal, and sees (he would see this if it were true) that certain features would be useful for human beings to have— useful from an evolutionary point of view: conducive to survival and reproduction—would naturally have the consequence that supernaturalistic belief would be in due course a human universal. Why shouldn’t he allow those features to be the cause of the thing he wants?—rather as the human designer of a vehicle might use the waste heat from its engine to keep its passengers warm.³

Van Inwagen’s argument is sound. Even if science could prove that religious belief has a genetic component that we inherit from our ancestors, that finding is not incompatible with belief in the reality of God or even the truth of the Christian faith. There is no logical reason to preclude that God could have used evolution to predispose people to believe in God in general so that people would be able to consider true belief when they hear the gospel preached. This is just one of many places where the supposed incompatibility of orthodox faith with evolution begins to fade away under more sustained reflection.

However, many Christian laypeople remain confused because the voices arguing that Biblical orthodoxy and evolution are mutually exclusive are louder and more prominent than any others. What will it take to help Christian laypeople see greater coherence between what science tells us about creation and what the Bible teaches us about it?

Pastors and People

In my estimation what current science tells us about evolution presents four main difficulties for orthodox Protestants. The first is in the area of Biblical authority. To account for evolution we must see at least Genesis 1 as non-literal. The questions come along these lines: what does that mean for the idea that the Bible has final authority? If we refuse to take one part of the Bible literally, why take any parts of it literally? Aren’t we really allowing science to sit in judgment on our understanding of the Bible rather than vica versa?

The second difficulty is the confusion of biology and philosophy. Many of the strongest proponents for evolution as a biological process (such as Dawkins) also see it as a ‘Grand Theory of Everything.’ They look to natural selection to explain not only all human behavior but even to give the only answers to the great philosophical questions, such as why we exist, what life is about, and why human nature is what it is. Doesn’t belief in the one idea—that life is the product of evolution—entail the adoption of this whole ‘world -view’?

The third difficulty is the historicity of Adam and Eve. One way to reconcile what current science says about evolution is to propose that the account of Adam and Eve is symbolic, not literal, but what does this do to the New Testament teaching of Romans 5 and 1 Corinthians 15 that our sinfulness comes from our relationship with Adam? If we don’t believe in an historical fall, how did we become what the Bible says we are—sinful and condemned?

The fourth difficulty is the problem of violence and evil. One of the greatest barriers to belief in God is the problem of suffering and evil in the world. Why, people ask, did God create a world in which violence, pain, and death are endemic? The answer of traditional theology is—he didn’t. He created a good world but also gave human beings free will, and through their disobedience and ‘Fall’, death and suffering came into the world. The process of evolution, however, understands violence, predation, and death to be the very engine of how life develops. If God brings about life through evolution, how do we reconcile that with the idea of a good God? The problem of evil seems to be worse for the believer in theistic evolution.

I have been a pastor for almost 35 years, and during that time I’ve spoken to many laypeople who struggle with the relationship of modern science to orthodox belief. In the minds of most laypeople, it is the first three difficulties that loom largest. The fourth difficulty—the problem of suffering and death—has not been posed to me as often by parishioners. Yet in some ways the problem of suffering goes along with the third question regarding the historicity of the Fall. Without the traditional view of the historicity of the Fall, the question of evil would seem to become more acute.

Therefore, below I will lay out three basic problems that Christian laypeople have with the scientific account of biological evolution. Nothing here should be seen as meeting the need for rigorous, scholarly arguments in answer to these questions. These are popular-level pastoral answers and guidance. As a pastor I have had to draw heavily on the work of experts. The first question, about Biblical authority, requires that I draw on the best work of exegetes and Biblical scholars. To answer the second question, about evolution as a ‘Grand Theory of Everything,’ I need to draw on the work of philosophers. When we come to the third question regarding Adam and Eve, I must look to theologians.

In short, if I as a pastor want to help both believers and inquirers to relate science and faith coherently, I must read the works of scientists, exegetes, philosophers, and theologians and then interpret them for my people. Someone might counter that this is too great a burden to put on pastors, that instead they should simply refer their laypeople to the works of scholars. But if pastors are not ‘up to the job’ of distilling and understanding the writings of scholars in various disciplines, how will our laypeople do it? This is one of the things that parishioners want from their pastors. We are to be a bridge between the world of scholarship and the world of the street and the pew. I’m aware of what a burden this is. I don’t know that there has ever been a culture in which the job of the pastor has been more challenging. Nevertheless, I believe this is our calling.

Next week, Keller begins to unpack the individual questions, beginning with how we can understand evolution in relation to a literal reading of the Bible.

Perusing the writings of atheistic scientists and philosophers like Daniel Dennett, one could easily get the impression that arriving at a simpler explanation for something equates to a revelation that things are “lower, cruder, and more trivial.” But at the heart of Barr’s critique is the observation that in fundamental physics and advanced mathematics, “simpler” does not mean more chaotic and inchoate, but rather more elegant and beautiful. Those who hold to a philosophical reductionism “overlook the hidden forces and principles” that govern the processes of cosmic evolution.

Barr’s article lays out the way that the work of scientists and mathematicians exploring the fundamental principles of physics (from Kepler to Einstein to those currently running the Large Hadron Collider in Switzerland) actually suggests “that order does not really emerge from chaos, as we might naively assume; it always emerges from greater and more impressive order already present at a deeper level.” This excerpt gives his first example, the starting point from which he guides us into strangely beautiful world of particle physics, and towards the discovery that “matter, although mindless itself, is the product of a Mind of infinite profundity and infinite simplicity.”

Fearful Symmetries

“Let’s start with a simple but instructive example of how order can appear to emerge spontaneously from mere chaos through the operation of natural forces. Imagine a large number of identical marbles rolling around randomly in a shoe box. If the box is tilted, all the marbles will roll down into a corner and arrange themselves into what is called the “hexagonal closest packing” pattern. (This is the same pattern one sees in oranges stacked on a fruit stand or in cells in a beehive.) This orderly structure emerges as the result of blind physical forces and mathematical laws. There is no hand arranging it. Physics requires the marbles to lower their gravitational potential energy as much as possible by squeezing down into the corner, which leads to the geometry of hexagonal packing.

At this point it seems as though order has indeed sprung from mere chaos. To see why this is wrong, however, consider a genuinely chaotic situation: a typical teenager’s bedroom. Imagine a huge jack tilting the bedroom so that everything in it slides into a corner. The result would not be an orderly pattern but instead a jumbled heap of lamps, furniture, books, clothing, and what have you.

Why the difference? Part of the answer is that, unlike the objects in the bedroom, the marbles in the box all have the same size and shape. But there’s more to it. Put a number of spoons of the same size and shape into a box and tilt it, and the result will be a jumbled heap. Marbles differ from spoons because their shape is spherical. When spoons tumble into a corner, they end up pointing every which way, but marbles don’t point every which way, because no matter which way a sphere is turned it looks exactly the same.

These two crucial features of the marbles—having the same shape and having a spherical shape—should be understood as principles of order that are already present in the supposedly chaotic situation before the box was tilted. In fact, the more we reduce to deeper explanations, the higher we go. This is because, in a sense that can be made mathematically precise, the preexisting order inherent in the marbles is greater than the order that emerges after the marbles arrange themselves. This requires some explanation.

Both the preexisting order and the order that emerges involve symmetry, a concept of central importance in modern physics, as we’ll see. Mathematicians and physicists have a peculiar way of thinking about symmetry: A symmetry is something that is done. For example, if one rotates a square by 90 degrees, it looks the same, so rotating by 90 degrees is said to be a symmetry of the square. So is rotating by 180 degrees, 270 degrees, or a full 360 degrees. A square thus has exactly four symmetries.

Not surprisingly, the hexagonal pattern the marbles form has six symmetries (rotating by any multiple of 60 degrees: 60, 120, 180, 240, 300, and 360 degrees). A sphere, on the other hand, has an infinite number of symmetries—doubly infinite, in fact, since rotating a sphere by any angle about any axis leaves it looking the same. And, what’s more, the symmetries of a sphere include all the symmetries of a hexagon.

If we think this way about symmetry, careful analysis shows that, when marbles arrange themselves into the hexagonal pattern, just six of the infinite number of symmetries in the shape of the marbles are ex-pressed or manifested in their final arrangement. The rest of the symmetries are said, in the jargon of physics, to be spontaneously broken. So, in the simple example of marbles in a tilted box, we can see that symmetry isn’t popping out of nowhere. It is being distilled out of a greater symmetry already present within the spherical shape of the marbles.”

In the full essay, Barr gives a richer description of how this most basic kind of symmetry is just one sort of order, and how even this form points to other much more complex kinds of symmetry whose properties may be described only through the tools of complex mathematics. As he says, “the symmetries that characterize the deepest laws of physics are mathematically richer and stranger than the ones we encounter in everyday life.” But even more important than the fact that such mathematical concepts exist and are beautiful, more important even than the way such esoteric mathematical symmetries have suggested imminently practical experimental projects, is the way they point to a universe that is anything but brutish and trivial, though its elegance may be hard to see:

“It is true that the cosmos was at one point a swirling mass of gas and dust out of which has come the extraordinary complexity of life as we experience it. Yet, at every moment in this process of development, a greater and more impressive order operates within—an order that did not develop but was there from the beginning. In the upper world, mind, thought, and ideas make their appearance as fruit on the topmost branches of an evolutionary tree. Below the surface, we see the taproots of reality, the fundamental laws of physics that shimmer with ideas of profound simplicity.”

In today’s video, Michael Ramsden discusses the importance and meaning of mystery in the Bible. It does not come from ignorance, as the word is often used in modern times, but rather it is mystery born out of insight and wonder, one that is informed by understanding the world around us. As Ramsden notes, Jesus’ use of children to describe the nature of faith isn’t meant to emphasize their ignorance, but rather their sense of trust for those who love them. Likewise, we should not be afraid to search out answers, as if knowledge will lessen our faith in God. Rather we should trust that our explorations will only strengthen our understanding in Him.

Today's video is courtesy of filmmaker Ryan Pettey, director/editor of Satellite Pictures and features physicist Ard Louis.

In today's video, Oxford physicist Ard Louis discusses the famous debate between renowned evolutionary biologists Stephen Jay Gould and Simon Conway Morris. Gould believed (and wrote in his book Wonderful Life) that if the "tape" of evolution were rerun, the chance that anything like human intelligence would emerge is essentially zero. In other words, humanity is here through random accident. Gould pointed to the work of Morris and fellow scientists in their research of the Burgess Shale as evidence for this view.

However, Morris himself disagrees, pointing to what is called evolutionary convergence. As Morris notes, there are numerous examples of identical features evolving multiple times throughout the history of life independently. Morris believes that if the tape of life were replayed, we would see something like humans emerge. A Christian might say, it looks like we were planned.

Some Christians might find Simon Conway Morris' viewpoint, with its implicit teleology, more attractive. Others, perhaps motivated by a high view of providence, may find Gould's emphasis on contingency equally congenial to their faith. What do you think?

Though some may believe that moving the science/faith dialogue forward is best left to scientists, scholars, and theologians, we at BioLogos recognize that our pastors play an invaluable role in the conversation. Across the globe, pastors are helping their congregations work through difficult issues of science and faith with honesty, insight, and a gentle spirit. To this end we present an ongoing series recognizing sermons (and the pastors who give them) that are helping to promote the harmony of science and faith. Today's sermon comes from Rev. Tim Keller, pastor of Redeemer Presbyterian Church. Click above to hear an excerpt. Below, is a brief summary written by BioLogos editorial staff. The full sermon can be downloaded here.

In tracing the story of the Bible, Dr. Keller’s previous sermons examined the early chapters of Genesis, which relate the events that lead to humanity’s fall from right relationship with God. Currently, he is exploring God’s redemption of the human brokenness in Paul’s epistle to the Romans. This particular message focuses on chapter two where the Apostle Paul exposes the hypocrisy of Law-observing Jews: while they judged Gentiles by the standard of the Law, they themselves failed to fulfill its requirements. He also asserts that outward performance of the Law by no means exempts them from God’s judgment or from the disease of Sin, which entered the human heart at the Fall. Keller affirms, therefore, that all are in need of a “regenerate new heart” through Jesus Christ, who perfectly fulfilled the requirements of the Law and who alone is able to accomplish this transformation through the power of his cross.

Paul’s message first illuminates what Keller identifies as the failure of religion. The church in Rome no doubt consisted of both Gentiles and Jews. With this in mind, Paul speaks to both groups. Up to this point, Paul has been highlighting the idolatry of the Gentiles. He then reorients his focus in Romans 2 to address the Jews, who were likely to stand in judgment of their gentile brothers and sisters because of the Jewish Law. He declares in verse one, “You, therefore, have no excuse, you who pass judgment on someone else, for at whatever point you judge another, you are condemning yourself, because you who pass judgment do the same things.” Keller explains that this statement exposes the hypocrisy of the religious who look to observance of an outward behavioral code for justification rather than to grace through Jesus, which leads to an inward observance of the Law. For example, although Law observers did not bow before physical graven images as the Gentiles did before faith in Christ, idols occupied their hearts. These inner idols, for both the religious Jews and present Christians, could take the form of power, career, achievement, etc. All in all, Paul demonstrates that religion fails since neither the moral nor the immoral person is perfect by God’s standards. Dr. Keller sums up this point nicely with this statement: “I’m not okay, you’re not ok.” There is not one person who measures up to the standard of the Law of God, and not one person, therefore, has a right to pass judgment according to it.

Dr. Keller then discusses why no one can measure up to the terrible beauty of God’s Law “no matter how good” one’s actions may be. Primarily, it is because the standard is not focused on performing the right deeds. Rather, the major sins described by Paul in Romans 1 include greed, insolence, heartlessness, etc. Although actions accompany such characteristics, they begin as inner attitudes of the heart. Often people read God’s ordinances at the behavioral level, as the religious Jewish people did, in an attempt to justify themselves as a moral person, but God’s requirements are much more demanding. This is revealed in Jesus’ Sermon on the Mount, for example, when he examines the Ten Commandments. He says in Matthew 5: 21-22 (NIV), “You have heard that it was said to the people long ago, ‘You shall not murder, and anyone who murders will be subject to judgment.’ But I tell you that…anyone who says to a brother or sister, ‘Raca,’ is answerable to the court.” In using the Hebrew word ‘raca’ meaning ‘nobody,’ Jesus is revealing that the sin of murder is birthed from a heart that devalues another person who is infinitely valuable in God’s eyes. Simply put, the Law of God is after a certain type of person whose right actions flow from a right heart. For example, the Law points to a person so filled with God’s love that they not only refrain from murder, but rather treat others as royalty. Keller continues as he explains the impossibility of such a standard for a human being, yet the Law demands it. What is more, people will demand a similar standard of others. Keller also emphasizes the Day of Judgment. Because God is just, he will hold a person accountable to either the standard of grace or to the standard that one person required of another. No person is perfect, and therefore, none will be able to stand in either God’s judgment or the judgment of their own heart. This creates the need for a transformed heart as Dr. Keller expounds in the final point of this passage.

In the last verses of Romans 2, the Apostle Paul relates the “failure of religion because of the terrible beauty of the Law” to the need for a regenerate heart. This is only possible through the circumcision of the heart in Christ by the Holy Spirit. Keller first explains the significance of circumcision. Circumcision was a physical distinction between the pagan cultures and the Jewish people who were in covenant with the God of Israel. On a deeper level, this act symbolized the consequence of disobedience to the covenant first established between Abraham and God: one would be cut off from the covenantal relationship with God. As Dr. Keller explains, all people have fallen short of the Law. For this reason, God sent Jesus, his son, to fulfill the requirements of the Law. He then died on the cross to receive upon himself the consequence of death that all deserved. Therefore, Paul argues that it is no longer one who receives physical circumcision who is saved, but one who receives the circumcision of the Spirit in Christ. Romans 2:28 (NIV) establishes this point saying, “A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code.” Finally, Dr. Keller explains the significance of the Old Testament Law: the perfect standard describes not a moral code, but our Savior Jesus Christ. Ultimately, one seeks to obey the beautiful Law which Jesus embodied, yet one receives grace in the times of failure, confident that Christ has indeed paid it all.

In today’s video, Pastor Brian McClaren discusses the idea of the “slippery slope”. As he notes, the metaphor itself is problematic, because we often assume that we are on the top of the slope to begin with, when in fact changing our views may help us ascend the slope, or to reach a new peak of understanding on the other side.

He also notes two dangers that face the science and faith dialogue. On one side is excessive confidence, when we are so sure of being right that we refuse to consider other ideas. But being too afraid of excessive confidence can lead to an insufficient confidence, where we feel incapable of knowing anything for sure. McClaren proposes that what Christians need, rather, is proper confidence, the confidence that we are moving ahead yet still willing to learn. This, he says, is what it means to be a disciple: to be interested in the truth and always learning, but always willing to be pensive again rather than set in our current knowledge.

"Reply the tape a million times ... and I doubt that anything like Homo sapiens would ever evolve again" (Stephen Jay Gould from "Wonderful Life", 1989 p. 289, Harvard University Press.).

With his standard panache, the late Harvard paleontologist Stephen J. Gould argued strenuously that evolution had no inherent directionality. It was a cosmic crapshoot - in no way destined to produce anything complex, self-conscious or human. We are mere accidents; a "tiny twig on an improbable branch of a contingent limb on a fortunate tree" ("Wonderful Life" p. 291). Highly fortunate indeed! Eons ago, a dinosaur-dominated earth held little promise for mammalian ascendancy (let alone primates or humans). Our distant ancestors might have remained little more than scurrying nuisances nipping at the feet of giants if not for a most unlikely calamity - a massive meteor strike which swept away the dinos and forever altered the earth's bio-saga. Who would have guessed?

Evolution's capricious nature seemed to represent a severe stumbling block for the Abrahamaic religious traditions. In their narrative, humans represented the culmination of God's creative work - the very purpose for creation itself. But evolution is an awfully shoddy way of enacting a divine plan. Gould delighted in annoying the faithful by emphasizing this very point:

"Odd arrangements and funny solutions are the proof of evolution - paths that a sensible God would never tread but that a natural process, constrained by history, follows perforce" ("The Panda's Thumb", 1980, pp. 20-1).

Theologians, however, were quick to point out that the chance element in evolution was neither new nor necessarily contrary to the Judeo-Christian view of God. Human history was replete with chance; evolution only extended the theme. Moreover, chance allowed for freedom - a virtue high on God's agenda. However theologically sound these retorts may have been, their force was often lost on the average believer. The accidental nature of human existence provided just another reason to reject evolution altogether in order to preserve God's special concern for humanity.

Gould was a talented science writer, but he overplayed evolution's whimsy. Increasingly, science is showing that the evolutionary process has many built in constraints which limit its possibilities and bias its pathways. Take, for example, the ubiquitous phenomenon of convergence - the tendency for highly diverse species to independently evolve similar adaptive (analogous, not homologous) traits. Most of us are familiar with the saber-toothed tiger, the scourge of our hominin ancestors. Less familiar are a group of South American marsupials called the thylacosmilids who independently evolved similar protruding saber-teeth. Convergence can also be seen in a number of specifically human traits. For example, we share a mode of locomotion, bipedalism, with birds, kangaroos, and some dinos. The lateralized and convoluted structure of our brains can also be found in octopi, this despite the fact that vertebrates and cephalopods diverged from one another over 450 million years ago.

In his book "Life's Solution" (2003, Cambridge Press) Cambridge Palaeobiologist Simon Conway Morris documents scores of examples of convergent evolution from insect body designs to the social systems of dolphins and chimpanzees (both fission-fusion). The important lesson is that there are only a limited number of ways that evolution can solve the adaptive problems posed by the earth's ecosystems. Time and again, evolution stumbles upon the same general design features from which to fashion adaptive traits.

Now add to this the Baldwin effect - an idea originally proposed in 1896 wherein organisms are posited to actively shape their own selective forces. For example, suppose some fairly intelligent primates begin fashioning tools, giving them access to new resources and a competitive advantage over non-tool users. Any genetic predisposition facilitating tool use would also be positively selected.

A severe limitation on Baldwin effects has always been the unpredictability of genetic mutation. For any heritable genetic changes to occur (so the thinking has always been) our tool wielding primate would just have to wait around and hope for a lucky "tool use" mutation to pop up. But maybe not. Two recent books, Jablonka and Lamb's "Evolution in Four Dimensions" (2005 MIT press) and Kirschner and Gerhart's "The Plausibility of Life" (2005, Yale University Press) discuss connections between recent work in genetics and Baldwinian processes. What if the primate's tool use actually raised the probability that a tool-relevant genetic change would take place which could then be passed along to offspring?

Recent genetic research (in a field called epigenetics) shows that experiences occurring over one's lifetime can produce heritable genetic changes. For example, mice exposed to two weeks of environmental enrichment (more social interaction, activity, novel objects to explore) show evidence of enhanced memory function (not surprising). More surprising is that their offspring also show evidence of enhanced memory even though they were never exposed to environmental enrichment (Journal of Neuroscience, 29, p. 1496). Thus, the increased environmental stimulation created a genetic change in the parents that was then transmitted to offspring. This change appears to involved altered patterns of gene regulation (how genes are turned on and off during development). Similar effects have been noted in humans (see European Journal of Human Genetics, 14, p. 159).

Convergence, epigenetic inheritance, and Baldwin effects are only a few of the mechanisms serving as directional constraints on evolution's pathways. In his review of the various factors affecting the evolutionary process, anthropologist Melvin Konner concludes:

"There are no intrinsic driving factors in evolution, but there are intrinsic constraints and canalized paths along which either evolution or development may more easily proceed" ("The Evolution of Childhood," Harvard Press, 2010, p. 59, emphasis in original).

Of course, none of these constraining factors guarantee our arrival on the evolutionary stage. They do, however, raise the odds that in time a complex, rational, self-aware creature capable of entertaining both scientific and religious ideas might emerge.

The more we understand evolution, the less it seems like neither the bogeyman that creationists fear nor the universal God-dissolving acid some atheists crave.

Though some may believe that moving the science/faith dialogue forward is best left to scientists, scholars, and theologians, we at BioLogos recognize that our pastors play an invaluable role in the conversation. Across the globe, pastors are helping their congregations work through difficult issues of science and faith with honesty, insight, and a gentle spirit.

Tim Keller, pastor of Redeemer Presbyterian Church. Click above to hear an excerpt. Below, is a brief summary written by BioLogos editorial staff. The full sermon, which we highly recommend can be purchased from Redeemer’s sermon store. Finally, if you know a sermon or podcast related to science and faith that has especially spoken to you, please let us know.

In the Garden of Eden, Eve is tempted to put her own desires ahead of God’s call for her life. The serpent tells her that if she eats of the fruit she can become like God: she, in essence, can become the master of her own fate. Similarly, as the New Testament begins, Satan comes to Jesus and tempts him in three different ways to become centered in self, rather than centered in the Father. Finally, Paul begins his great treatise, his letter to the Christians in Rome, with the same thought. We all, like Eve, but not like Jesus, have tasted of the fruit, and Dr. Keller in his penetrating style expounds.

This week’s sermon continues to evaluate the heart of humanity, which first is revealed in Genesis, and later is expounded upon in Romans 1: 18-32. The Apostle Paul’s letter to the church in Rome presents a clear picture of both God’s revelation in the world, and humankind’s suppression of the truth. Exploring the message of Paul, Dr. Keller reveals that within each heart is the knowledge of our God, the factory of our idols, the hardening of our humanity, and the capacity for endless praise.

Foremost, the knowledge of God resides deep in the soul, but humans continually suppress this truth. It is the knowledge that God is Creator to whom all are completely accountable and on whom all are forever reliant. However, as Paul reflects on humanity in Romans 1: 21 (NASB), he claims that “though they [people] knew God, they did not honor Him as God or give thanks…” Dr. Keller explains that an unthankful heart is not merely bad etiquette; it generates the false reality of self-sufficiency and fails to recognize utter dependence on God for all things. Our sinful nature desires to maintain control, but true acknowledgment of God demands that we submit to his will rather than our own. Keller further makes the point that many people can believe in an impersonal God who gives all a free pass into heaven, but very few people wish to believe in the relational God of the Bible who demands all of their soul. For this reason, people suppress the truth about God and withhold his praise.

Inevitably, this act of turning away from the truth of God leads to the manufacturing of idols within the heart as one begins to worship a created thing rather than the Creator. Dr. Keller explains that people are “telic,” which means that they “need to live for something.” There is something in every person’s life that holds their worth, hope, and allegiance. If this something or someone is not the living person of Jesus Christ, one will be enslaved to idols. From wealth to marriage to morality, the Apostle Paul makes it clear throughout all his letters that these idols may take numerous forms. For example, he says in Romans 1:23 (NASB) that they “exchanged the glory of the incorruptible God for an image in the form of corruptible man and of birds and four-footed animals and crawling creatures..” The stark reality is this: God deserves all of our love and all else is futile worship of idols.

Next, the sermon explores how the worship of idols causes the heart to harden. Dr. Keller explains how idolization will ultimately strip a person of his or her humanity. In speaking about this very thing, the writer proclaims the truth in Psalm 135 (NASB) that idols are “the work of man’s hands. They have mouths, but they do not speak; they have eyes, but they do not see; they have ears, but they do not hear…Those who make them will be like them, Yes, everyone who trusts in them.” It is apparent from this verse that an idol will consume the heart’s desire. In this place, the person’s will becomes utterly subject to the object and conformed to its dead image, rather than conformed to the image of the living God.

Lastly, Dr. Keller illuminates the remedy for all the perpetual idols in our hearts. He affirms that in order to stop worshipping these idols, one must do as the angels do in heaven: endlessly praise and worship God. He then references 1 Peter 1: 10- 12, which describes how angels long to look into the things concerning the gospel of Jesus Christ. In other words, Dr. Keller explains, the angels deeply desire to gaze upon the beauty of what Christ has done for all humanity by his death on the cross and resurrection from the grave. When we too see Jesus and glorify him as the One who gave it all for us, we will finally be saved from the destructive power of idols.

While these are indeed complex questions, some of the problems do stem from misunderstandings about what randomness means in a scientific sense and what role it plays in evolution. To help clarify some of these details, we offer these resources.

The “Randomness” installment of our Distinctions series (first posted earlier this year) looks at some of the basic misconceptions about the role of randomness in evolution. While it is understood by many simply to mean blind, undirected and purposeless, in truth, randomness is far more complex and awe-inspiring than this overly-simplified definition. Whether through genetic mutations or the combinations that occur between sperm and eggs, these processes can be seen as the continual unfolding of something that is decidedly not random--creation itself. Randomness, in essence, generates certainty. This is further illustrated in the second video.

In the clip “Randomness” from the upcoming film A Leap of Truth by Ryan Pettey, Richard Colling, Ard Louis, and John Polkinghorne offer several examples of random processes leading to order rather than disorder. As Dr. Louis points out, the scientific definition of “randomness” is quite different from our everyday understanding of the word. In fact, random generation is the most efficient way to generate complexity. Polkinghorne further notes that we live in a world where the balance of random mutations is almost perfectly tuned for fruitful life on Earth. This, we learn, is God's process: Randomness given time, can lead to that which is nearly certain.

This is beautifully illustrated in the following re-post from last year. Here, in a blog called "That's Random," Kathryn Applegate offers two examples of random motion leading to certainty in the process of assembling a virus. Because random processes can lead to that which is almost certain, it is not at all surprising that this has frequently been used by God over billions of years to create order out of chaos--God's creation, by God's way, in God's time.

That's Random

You hear it all the time: “That’s so random!” When used by people of my generation, the word “random” can simply mean “cool” or “surprising.” Or it can mean something like “disconnected,” as in the phrase, “I had a random thought” (which returns 189,000 hits on Google, by the way—random!).

Despite this usage, most of us know that randomness has something to do with probability, and that it often implies a lack of conscious intentionality. But what do mathematicians and scientists mean when they say something is random? Can a random process lead to an ordered, even predictable outcome? Is there evidence that God makes use of random processes to fulfill his creative purposes?

These are big questions, and we won’t address them all today. But I think randomness is an important topic to cover for two reasons: 1) it is integral to many processes in biology (and math, physics, chemistry, etc.), and 2) it is commonly misunderstood to be incompatible with Christianity.

As I said above, most of us know that randomness has something to do with probability. If you pick a card “at random” from a shuffled deck, you have a small probability of drawing an ace (4 out of 52, or a 7.7% chance). If you flip a coin, you have an equal probability of getting heads or tails.

Randomness also seems to imply a lack of intentionality or purposefulness. After all, you might hope for an ace when you draw a card, but you can’t choose one on purpose. You might call heads when you flip a coin, but you can’t know beforehand what the outcome will be. Thus the outcome is indeterminate, but is it purposeless? Not necessarily. Indeterminacy simply means the result cannot be predicted from the outset.

It should be noted that indeterminacy does not imply that God does not have foreknowledge of future events. Christians ought not to be uncomfortable with the idea of God interacting with his creation through chance. We often describe a seemingly-random (i.e. unplanned by us) sequence of events as being “providential,” or planned by God. A good introduction to the way divine action could drive physical processes can be found in this Question.

In biology, it is very hard or impossible to calculate precise probabilities for most processes, so when we say a process is random, we typically mean it is extremely unpredictable. Eventually we will discuss randomness within biological evolution, but first we must consider some simpler processes, like the self-assembly of a virus.

Viruses are remarkably efficient entities. Coiled tightly within a protein-based shell is a small amount of DNA needed for self-replication. The shell, called a capsid, is made of many repeating protein subunits and is therefore highly symmetrical (see figure). Important biomedical insights have certainly been gleaned from structural studies of viruses, but viruses also teach us about the emergence of order from non-order.

The virus life cycle has four main steps: 1) enter a host cell, 2) hijack the cell’s replication and translation machinery to make many copies of itself, 3) assemble into many virus particles, and 4) exit the cell to invade another host.

When I first learned about this process, I found it very hard to believe it just “happens.” The idea that a bunch of molecules bumping into each other inside a crowded cell could spontaneously assembly into a fully-functional virus seemed a bit far-fetched. Many viral capsids have over 100 protein subunits that must interact with each other in just the right way, or it won’t work. Surely there must be something driving this process, right?

There is! Random motion. I had to see it to believe it. I distinctly remember sitting in class during my first year of graduate school when the professor demonstrated self-assembly of a virus using a 3D model as shown in the following video. In less than 30 seconds, you can watch a jumbled heap of proteins become a beautifully ordered structure.

As the narrator explains, sub-assemblies form and break apart en route to the most stable structure, the full capsid. As the sub-assemblies begin to form, further associations with free subunits become more favorable and as a result occur rapidly, while the final steps may take considerably longer. While the subunits in the model are rigid, in reality the proteins take on multiple conformations, allowing the capsid to “breathe.”

Amazing as it is, the system we just considered—one virus capsid in a jar—is pretty simple. One wonders how self-assembly can happen in a crowded cell, where there are countless other molecules diffusing around, potentially getting in the way. We can’t directly see how it happens in a cell, but we can reconstitute the process in a test tube using different combinations of constituent molecules.

Consider two viruses, where each protein subunit in one virus is the mirror image of the corresponding subunit in the other. Putting the two viruses together by hand would be pretty tricky, because the constituent parts look so similar. But random motion can do the job in short order:

From this model, we can see clearly, in real-time, how distinct complex structures can arise from their parts randomly interacting with one another. Many large viruses also use special scaffolding proteins to assist in the assembly process, and some even use their own genomes as a scaffold. In addition, two closely-related viruses that happen to infect the same cell can exchange parts to create a new virus. This is one way viruses can evolve quickly to evade the host’s immune system.

Here we have seen how viruses demonstrate a principle inherent in God’s world—that order can emerge out of chaos from random processes.

1. From Scot: Could you explain the difference between creationism, intelligent design, and "evolutionary creationism"?

“Creationism” is one of those words that almost always needs clarification. For many, “creationism” is synonymous with Young-Earth Creationism, the view that the Genesis narratives are to be taken literally. This view holds that the entire cosmos is around 6,000 years old, that the fossil record was laid down almost in its entirety during a literal, global worldwide flood, that God created humans directly out of dust, and that Adam and Eve are the progenitors of the entire human race. The organization Answers in Genesis is probably the best-known proponent of this view.

Old-Earth Creationism typically holds to a local flood, and accepts Big Bang cosmology. Despite agreeing with mainstream science on these issues, they deny evolution: they believe that the vast majority of species (and especially humans) were independently created by God during earth’s long history. Old-earthers also hold to a literal Adam and Eve as the progenitors of our entire species. Reasons to Believe is the best-known organization that promotes this view. You can read one of my (somewhat technical) critiques of their anti-evolutionary genetics arguments here.

Intelligent Design (ID) is a view that many feel is a form of creationism, though the ID Movement itself often rejects the label, claiming that it is strictly an alternative scientific view. The ID Movement is a “Big Tent” approach for all and sundry who reject at least some part of evolutionary biology. As such, there are Young-Earth Creationists, Old-Earth Creationists, and others within the movement. The main ID view is that some features of life are too complex to be the result of evolution, thus indicating that they were “designed” – a word that functions as the equivalent of “created” within this group. The Discovery Institute is the best-known organization for promoting ID. I’ve spent a lot of time critiquing the ID movement, and you can find much of that material on the BioLogos web site (do an author search there using my name).

Despite their (large) differences, all of the above positions deny some aspect of modern science. The only Christian perspective on origins that fully accepts mainstream science is the Evolutionary Creation / Theistic Evolution view. This view holds that science is not an enemy to be fought, but rather a means of understanding some of the mechanisms God has used to bring about biodiversity on earth. This view accepts that humans share ancestry with all other forms of life, and that our species arose as a population, not through a single primal pair. There are different views within the EC community on whether there was a historical couple named Adam and Eve – some hold that there was, and that they were selected by God from a larger population as representatives. Other folks in the EC community feel that Adam and Eve are typological figures, such as a representation of the failure of Israel to keep the covenant. The science (human population genetics) is clear that our species arose as a population, and that is what I have focused on (since that is my area of expertise). I try to leave the theology to others, but often folks want to talk theology on these points, not science.

2. From Paige: What has been the most compelling evidence for you personally that has solidified your position as an evolutionary creationist?

Well, the evidence is everywhere. It’s not just that a piece here and there fits evolution: it’s the fact that virtually none of the evidence we have suggests anything else. What you see presented as “problems for evolution” by Christian anti-evolutionary groups are typically issues that are taken out of context or (intentionally or not) misrepresented to their non-specialist audiences. For me personally (as a geneticist) comparative genomics (comparing DNA sequences between different species) has really sealed the deal on evolution. Even if Darwin had never lived and no one else had come up with the idea of common ancestry, modern genomics would have forced us to that conclusion even if there was no other evidence available (which of course manifestly isn’t the case).

For example, we see the genes for air-based olfaction (smelling) in whales that no longer even have olfactory organs. Humans have the remains of a gene devoted to egg yolk production in our DNA in exactly the place that evolution would predict. Our genome is nearly identical to the chimpanzee genome, a little less identical to the gorilla genome, a little less identical to the orangutan genome, and so on – and this correspondence is present in ways that are not needed for function (such as the location of shared genetic defects, the order of genes on chromosomes, and on and on). If you’re interested in this research, you might find this (again, somewhat technical) lecture I gave a few years ago helpful. You can also see a less technical, but longer version here where I do my best to explain these lines of evidence to members of my church. For those wanting even more info, a few years ago I recorded a series of lectures given to my non-majors, intro biology class that explored evolution and Christian responses to it in depth.

3. From Rob: I have trouble with randomness in natural selection. Why is it essential in scientific terms that evolutionary development is random? How does that fit with the notion of a God who is involved in the world? …Random evolution would not be theism (or it wouldn't Biblical Christianity). It would be deism; the Great Clockmaker who set everything in motion and then kept hands off. Why is randomness essential scientifically, and how does a Christian accept it theologically?

I think you mean randomness in mutation: natural selection is anything but random (it’s a process whereby certain variants in a population reproduce more successfully than others). Evolution has a random component (mutations arise that may be detrimental, neutral or beneficial) and an emphatically non-random component (the different variants within a population do not all reproduce at the same frequency, meaning that the next generation will not be exactly like the previous one). So, as a whole, evolution is not random since it has a strongly non-random component. Evolution is actually remarkably good at producing similar results over and over again: consider how similar ichthyosaurs (descended from terrestrial reptiles) and dolphins (descended from terrestrial mammals) are. That’s the non-randomness of evolution at work. Some evolutionary creationists have argued that this non-randomness of evolution is a way that God uses evolution to shape His creation (the best work on this topic is Life's Solution by noted Cambrian paleontologist Simon Conway Morris).

4. From HMV: I agree with you that the evidence seems to point to evolution being true. I've read Biologos and the old Evolution and Evangelicals blog. I've read books where people try to rework theology in light of this scientific knowledge. And yet, I'm left feeling confused and unsatisfied about doctrines like sin, the Fall, salvation, etc. What about you--have you found a satisfying way to maintain your evangelical theology in light of evolution?

This is a tricky question, because it hinges on the inherently subjective term “satisfying.” What I might find satisfying you might not – and in order to answer the question I have to guess at what you mean by it.

Personally, the concept of Divine accommodation has been helpful to me. This is a theology that has a long heritage in Protestant circles (e.g. Calvin). In a nutshell, it’s the idea that God, in his grace, brings himself down to the level of the audience he is communicating with. For Genesis, that audience is an ancient near-eastern culture, not our modern scientific one. For Genesis, my view is that God wants to communicate that he is the Creator of all that there is, that he has given humanity a special image-bearing role within it, but our sinfulness has broken that relationship, et cetera – but that he doesn’t see a need to give them a science lesson first. I would recommend Denis Lamoureux’s book I Love Jesus & I Accept Evolution and, though not directly related to science, Peter Enns’ book Inspiration and Incarnation may also be helpful to you (it certainly was to me).

5. From Chris: From the perspective of an evolutionary creationist, what meaning and value do you extract from the creation accounts in Genesis and why would they be important for the Christian faith if they can't be taken literally?

See the answer above – I see the Genesis narratives as God graciously reaching down to an ancient culture in order to communicate to them that he is their creator, that they are alienated from him, and that he desires that they be restored to fellowship through his offer of covenant with him (ultimately pointing to the need for God to step into history himself as the One who can keep the covenant on our behalf).

6. From Paige: I'll never forget sitting in one of Dr. Charlie Liebert’s classes several years ago and hearing him ask the question: "What came first, death or sin?" If we believe that there was no death before sin, it causes a wrinkle in our ability to hold to the theory of evolution. As a scientist, this question caused him to reexamine the evidence. How have you personally dealt with this "wrinkle?"

Yes, if you believe that no death of any kind (plant, animal, bacterial) occurred before human sinfulness, then this precludes an evolutionary view, since the fossil record is (obviously) a record of things, well, dying. If you hold that no human death came before sinfulness, then it depends on what you call human (there is a gradation of forms leading up to the modern human skeleton in the fossil record, as well as the overwhelming genetic evidence that we arose through an evolutionary process) and what you consider sin (i.e. when did we become accountable to God for our actions?). There is also the long-standing observation that God decrees that Adam and Eve will surely die the day they eat of the fruit – and then they live for several hundred years after the fact. I’d also recommend reading through Romans 5:12 – 8:17 (which, as you know, is all about Adam, sin and Christ as the second Adam) and making a mental checklist of how Paul uses the term death in this passage. References to physical human death are in the minority – suggesting that Paul’s understanding of what is going on in Genesis has a lot more nuance than a simple literal reading would imply.

7. From Jane (from her husband, an atheist): All of the questions posted so far approach the topic from the viewpoint of assuming belief in a god. As an atheist, I don’t share that assumption. (For those who might not appreciate it, evolution offers a mechanism for understanding the existence of living organisms that doesn’t require the existence of a god.) If you transitioned from an anti-evolutionary/pro-intelligent design view to an evolutionary creationist view a few years ago,” why didn’t you keep going and just embrace evolution and drop the theistic aspect?

Your question implies that there is a natural trajectory from accepting evolution to rejecting God. As a theist, specifically an evangelical Christian, I don’t agree with this point, though I understand where you are coming from. Let me explain.

Your assumption, that “evolution offers a mechanism for understanding the existence of living organisms that doesn’t require the existence of a god” holds weight only if one has the view that “natural explanations” and “theistic explanations” are a zero-sum game. This is a God-of-the-gaps approach, where God has less and less to do as we understand more and more how nature works (and a view I reject). Logically, if I held this view I would view science as an inherently evil activity, since any natural explanation diminishes the activity of God from this viewpoint. Your view is also one that science cannot establish as correct, since science cannot speak to the absence of divine action in an observed phenomenon.

If, on the other hand, one believes that “natural explanations” reveal the means by which God ordains and sustains his creation, then “natural explanations” are not a threat to theism at all, but rather a window into the ways God acts in the world. This is the view I hold, and it too is a view that science cannot establish. Both theistic evolution and atheistic evolution are philosophical / theological interpretations of what science can establish: evolution.

As for “drop(ping) the theistic aspect” – this would imply that my faith was based on a particular understanding of creation such that I would question my faith when I questioned the mechanism of creation and/or my interpretation of Genesis. This wasn’t really an issue for me, since my faith was, and is, based on believing that Jesus of Nazareth is in fact the resurrected Lord of the entire world (to roughly paraphrase how N.T. Wright puts it) and that the resurrection is God the Father’s vindication of Jesus’ messiahship (as a sinless, suffering servant that, mystery of mysteries, turns out to be God Himself, incarnate). None of that belief was ever predicated on a specific interpretation of Genesis with respect to scientific details, and as such, accepting evolution as a mechanism by which God creates did not alter those beliefs. (If you’d like to see a rational, historically-rooted investigation of the credibility of the resurrection, N.T. Wright’s The Resurrection of the Son of God is the standard by which others are judged.)
