“I will put enmity between you [Satan] and the woman, and between your offspring and her offspring [Jesus]. He shall bruise your head, and you shall bruise his heel” (Genesis 3:15—read Genesis 3:1-21).
On the same day of the first sin came the first preaching of the Gospel. God had created the world and all that exists. He had planted a garden, and in that garden he put the first man and the first woman. They were to care for the garden and all it contained, both plants and animals. They were to be fruitful and multiply and fill the earth. They were to rest every seventh day. Any of these commandments they could have broken for the first sin. Instead, they ate the fruit of a tree that had been forbidden to them. This act of rebellion against God’s clear commandment caused them to know what evil is. They feared God and tried to hide from him. They looked for someone else to blame for their sin. Being separated from God, they were spiritually dead, and eventually they would physically die.
Yet when God confronted them, they did confess their sin. Adam tried to blame Eve (and also, indirectly, God—“the woman You gave me”), and Eve tried to blame the serpent. They both pointed the finger of blame elsewhere, and the poor serpent had no finger to point. But they confessed: each of them admitted, “I ate.”
Satan had taken the form of a serpent to tempt Eve—and through her, Adam—to join him in his revolt against God. God let Satan know that the shape he had taken foretold his fate. He would crawl on the ground and eat dust—in other words, Satan was going to lose. On the other hand, God already had a plan to rescue and redeem Adam and Eve and their descendants. As Satan used a tree to defeat them, so God would use a tree to defeat Satan—the tree of the cross. Satan did not gain allies in his revolt: he gained enemies. He would cause harm to humanity, and even to God when God became human. God would suffer on the cross, but his suffering was small compared to Satan’s suffering. His suffering led to victory; Satan’s head was crushed in the victory Christ won on the cross.
Christians are called to bear fruit for the Lord. His commandments tell us why he made us. They tell us how to love and honor him, and they tell us how to love and serve one another. Without God’s redemption, though, no one can bear fruit pleasing to the Lord. We are like an orchard of bare, dead trees. We are fruitless. We are worth nothing except as fuel for the fireplace.
On one dead tree, Jesus changed all that. On the dead wood of the cross, Jesus gave life to his people. Now all those who trust in Jesus have their sins forgiven and removed. All those who trust in Jesus are clothed in his righteousness. All those who trust in Jesus bear fruit pleasing to God, and, as a result, we are certain of a place in his kingdom. We will live forever in his new creation.
Adam and Eve tried to clothe themselves with fig leaves because of their shame. God provided them instead with garments of animal skins. The death of those animals pictured the death of Jesus, because by his death and through Baptism he clothes us in his righteousness.
Adam and Eve heard the promise about Jesus, believed it, and were redeemed. We also hear this promise, believe it, and are redeemed. Nothing has changed since the beginning, expect for this: Jesus has come and has kept the promise. Thanks be to God! J.
