Genesis begins with God making humanity in his image, giving male and female the task of ruling over the earth as God’s representatives. Creation and new creation form the whole Bible story: human beings were made to reflect God’s goodness, kindness, mercy, justice, and character into the land and among the creatures. Human rebellion corrupts that image. Instead of reflecting God, good, and life, humanity reflects death back to death.
The covenants with Abraham, Sinai, and David reveal who God is before Christ comes as the true image of God. The commandments matter, but basic morality does not restore the image of God. Honoring parents, not murdering, not committing adultery, not stealing, not lying, and not coveting can create a decent society. That kind of society, however, does not necessarily describe a Christian people. It can simply describe respectable people who have learned not to be wild, chaotic, or disorderly.
The Torah itself shows that rules cannot cure hard hearts. Its relatively small number of commandments cannot possibly regulate every human situation, and many of them concern worship, sacrifice, purity, priests, and festivals rather than social morality. Slavery and divorce show that God sometimes regulated broken institutions because of the hardness of human hearts. Moral rules do not do any good for people whose hearts remain hard.
Sinai reveals the God humanity is meant to image: the God of thunder, lightning, smoke, fire, and holy terror, and also the God who says, “Make a sanctuary for me, and I will dwell among them.” Yahweh is compassionate and gracious, slow to anger, abounding in love and faithfulness, forgiving wickedness, rebellion, and sin. Yet Yahweh also does not leave the guilty unpunished. Mercy and judgment cannot be separated according to human preference.
The cross resolves what looks like a contradiction. Jesus Christ brings the unapproachable God into the midst of his people, and the cross deals with sin without destroying sinners. Mere decency lowers God’s standards to something manageable, then congratulates itself for not having killed anybody. Jesus goes beneath behavior to thoughts, motives, emotions, desires, and rebellion. Moral effort cannot make fallen humanity fit for the image of God any more than practice can make an ordinary person an NBA player or jump the Grand Canyon. New creation comes only through the cross, where God roots out wicked desire and brings death and resurrection together.
Key Takeaways
- 1. Morality cannot heal hard hearts The law can restrain chaos and establish a measure of social order, but it cannot create a new heart. Respectability can hide rebellion beneath good behavior and public virtue. The cross reaches where rules cannot reach: the desires, motives, and false worship that produce sin. [49:29]
- 2. Decency is not Christian new creation The second table of the law can produce orderly neighborhoods, faithful families, and honorable reputations. Those goods remain good, but they do not by themselves reveal Christ or restore the image of God. Christianity is not “good little boys and girls,” but sinners being remade through the crucified and risen Christ. [50:49]
- 3. God is holy and merciful Sinai refuses every attempt to make God merely comfortable, predictable, or useful. Yahweh comes in thunder and fire, yet chooses to dwell among his people in compassion and faithfulness. God’s mercy never means indifference to guilt, and God’s judgment never cancels his steadfast love. [53:33]
- 4. The cross holds judgment and mercy The cross is the one place where God deals truthfully with sin and sinners survive the process. Christ does not merely make moral improvement possible; Christ bears judgment and opens the way for new creation. The unapproachable God comes near there without compromising holiness. [56:33]
- 5. Christ restores God’s broken image Humanity keeps trying to image other gods because false gods seem easier, simpler, and more manageable. Christ alone is the true image of God, and life in him is not self-manufactured moral success. The cross continues to expose and root out every wicked desire that distorts God’s image in his people.
