“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.

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 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.

The ordained and blessed tradition of marriage is established in Genesis 2: 18-25. This passage communicates important ideas, Dr. Keller affirms, about both marriage seeking and marriage executing. When considered, these concepts will allow one to be successful in both areas.

Foremost, Adam’s response to his wife highlights marriage’s potential to be idolatrous. When God presents all other creatures before Adam in the garden, not one is considered to be a suitable helper. Therefore, the Lord creates Eve from the rib of Adam and brings her to him. Upon seeing the woman, Adam exclaims in verse 23, “This is now bone of my bones, and flesh of my flesh.” Adam is expressing, in effect, that he has found at last the helpmate he longed for—by discovering Eve, he is finding himself. Marriage, then, is so fulfilling that there is a danger of idolization of one’s partner. Often, the temptation is to receive love, affirmation, respect, and even a foundation in life from their spouse, rather than from God—the very source of all these things. However, no human relationship “can bear the weight of those expectations,” and the marriage will be crushed. In addition, there is a tendency for unmarried persons to commit idolatry when they either yearn for marriage to complete them or search for that “perfect” marriage partner. God alone can meet these desires for perfection and wholeness. The problem, then, is not in loving one’s spouse too much or in wanting a blissful marriage, but in the smallness of one’s love for God in proportion to the other.

Next, God’s identification of Eve as Adam’s helper reveals the long-enduring patience that marriage requires. This word helper is often used to refer to military reinforcements throughout the Bible. The man and the woman as a couple bring to each other a strength that is not had by either of them as individuals. However, they are not just helpers, but suitable helpers. The word suitable in the Hebrew, Dr. Keller explains, is closely translated to mean ‘like opposite.’ In other words, the woman is like him, yet not him. Like two puzzle pieces, Dr. Keller says, God designed male and female as perfect complements to one another. Thus, marriage involves two people coming together with equal, but distinct strengths, and they enter into a tight relationship. So close is this communion that it is described as becoming “one flesh” in Scripture. In this closeness, necessary “head-butting” occurs as the spouses are challenged by one another to become the persons God made them to be. For this reason, it is essential to have the patience to bear with one another throughout this long journey of growth in life.

Then, there is a supernatural humility in the idea of marriage as conveyed by Genesis 2: 18(NASB) when God says, “‘It is not good for the man to be alone.’” Although Adam is in Paradise with God himself, God seems to indicate that Adam is lonely. According to Dr. Keller, the only explanation is that God specifically made Adam to need someone else in addition to himself. This is the most humble, unselfish act one could imagine—that the God of the universe would make people to need others as well.

As Dr. Keller concludes his sermon, he discusses how marriage portrays the relationship God seeks with his people—God as the bridegroom and his people as the bride. It is essential to understand that God desires to be the intimate helpmate to every person, even their spouse who is faithfully committed to their growth. Without God, one will never become who he or she was created to be. In claiming to be his people’s husband, as in Isaiah and Jeremiah, God is saying, “I have given you my heart.” For this reason, God sent his only son, Jesus Christ: to win back the heart of his wayward bride. Therefore, those who accept his love and put on the wedding ring of faith inherit all that is found in Christ. Ultimately, the Bible begins with a wedding, and it ends with a wedding—the marriage supper of the Lamb that will fill the world with the children of God.

Genesis 2:2-17 places an interesting emphasis on work—not only does God work to bring about all creation, but also, man is called to the task of caring for God’s world. Dr. Keller believes this passage provides an important assumption, a purposeful direction, a resulting burden, and a necessary provision concerning the work.

First, because God is described as working, one can conclude that work reflects a significant aspect of God’s character. Therefore, when humans perform various tasks, they are reflecting the image of God. If working does indeed reflect his image, Dr. Keller states, then there is an intrinsic dignity to manual labor no matter what the occupation. This concept reveals the goodness of ordinary life. Whether simply gardening to produce food or cleaning a space to produce order, people are meant to rejoice in the responsibilities that daily life brings.

Then, Dr. Keller explains that the duty of humankind to care for God’s garden reveals the aim of all work. In order to garden properly, one must meddle with the natural state of things to bring about fruitfulness and prosperity. This may include clearing the ground to expose it to sunlight or trimming back plants to stimulate growth. The gardener cannot simply standby like a “park ranger” and let things freely develop—he or she must creatively order the garden in such a way that all plants thrive. In the same way, all work involves, as Dr. Keller puts it, “rearranging the raw material of a particular domain [in order] to draw out its potential for the flourishing of everyone.” He strengthens his point by applying this definition to the work of writing music. Music, he says, is created when the raw material of sound is structured in such a way that it brings meaning to human life. Overall, God has given all people the ability to express creative energy in the service of others, and that is the intended goal of work.

Next, the Genesis text reveals the burden of work. When the curse of the Fall came upon Adam and Eve, death entered the world. According to Dr. Keller, this is more than just a physical death that came to humanity. He compares the human condition to the second law of thermodynamics (which states that the universe is becoming more disordered) in order to demonstrate that people are falling apart physically, culturally, spiritually, vocationally, etc. People are constantly caught in the tension between their efforts to accomplish tasks and the unstoppable force of death that causes all things to degrade. Furthermore, he says that one can neither have a cynical view nor a romantic view of work. A person must recognize the goodness of work, yet keep in mind that it is still difficult and laborious. Although each person has a specific vocation through which to serve the world, he or she cannot always fulfill this calling because he or she must work to survive as well. This is the very heart of the frustration and burden of humanity’s calling to work in this fallen world.

Finally, in the midst of this struggle and tension, God has given humans this provision: rest. Genesis 2:3(NASB) puts forth the statement that, “…God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.” The Bible shows that this rest has been given as a free gift to all people, and it is not a provision that needs to be earned. According to Dr. Keller, this gift is the rest of peace and the rest of hope. It is the rest of peace because Christ has offered his love that assures believers in their significance. People no longer have to bear the burden that somehow their performance in their job or career determines their value as a human being. Likewise, it is the rest of hope because believers will one day have the ability to realize their dreams—an invention, a painting, a novel—when God makes the new heavens and the new earth. Therefore, a Christian need not be dismayed by the broken dreams in their heart during this lifetime, for one day, those things too will be accomplished. Now, through Jesus Christ, all can enter into the deep peace that their soul so desires and find true rest in work.

ADDENDUM: Please note, although we do invite your comments as we explore the theological richness of God's word in the sermon series, the comments will be restricted to Christians who are genuinely seeking to enter into a deeper and more meaningful relationship with God. Those who are not Christians but are seriously seeking to explore the Christian faith as a possibility for their own lives are also very welcome to raise questions and make comments. However, this will not be a place to belittle Christianity. We ask that our atheist friends respect our purpose here. We realize that you think Christianity is irrational and we are willing to engage the profound rationality of our faith, but this is not the place to discuss that with you.
