Genesis 3:15: I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel.
Genesis 3:15 is the first prophecy in the Bible. God declared war on Lucifer. There would never be peace between His regenerate children and the unregenerate children of the devil. It was a battle to the death. The women would one day give birth to a child that would crush the serpent’s head. This woman was Mary, and this child would be Jesus.
God, who sees the end from the beginning, declared the final defeat of sin and the final redemption of His elect. This promise begins here and travels through redemptive history; through Abraham, Moses, David, and the Prophets. But God would not accomplish this in the way one would think. He could have crushed Lucifer under the weight of His wrath at any moment for any reason. Instead, He gets in the ring with Lucifer and beats him in his own boxing match. He defeats death with death.
Christ received God’s curse of death upon Himself that we might receive God’s promised redemption. Under God’s curse, Jesus took the full weight of God’s wrath against sin (Isa.53). God punished the sins of His elect on His own Son (Ps.22:1). Christ’s sacrifice was as a satisfactory and vicarious atonement for sin. It was satisfactory because Jesus was perfect and God required a sinless sacrifice. It was vicarious because Jesus was taking God’s wrath against our sin, not His own. As a substitute, He took our curse.
“The Lord God made for Adam and for his wife garments of skins and clothed them (Gen.3:21).”
Christ was, in fact, innocent. His atonement for sin was accepted by God. In raising Him from the dead, the Father declared that Jesus’ payment for sin was accepted. Through faith in Christ, we can be accepted by God. As God made tunics for Adam and Eve to cover their nakedness, Jesus too can cover our sin with His righteousness. His Atonement is actual and permanent. God will see our sin no more when we trust in Christ alone for our Salvation.
