Jesus In The Old Testament: He Will Crush Satan's Head

Genesis 3:15; And I will put enmity between you and the woman, and between your offspring (seed) and hers; he will crush your head, and you will strike his heel. 

These words from God - spoken to Satan in the garden of Eden - state that Jesus would crush Satan's head, Satan's power, Satan's curse, and Satan's work. These words from God - spoken during the first days of creation, moments after man first sinned against God - point to the cross. These words tell us that God would send a person - Jesus - to come and redeem us and to save from the sin of mankind. These words tell us that Jesus would come and break every bond of Satan.

Hebrews 2:14; Since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death—that is, the devil.

1 John 3:8; The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work.
