It is written:
“And I will put enmity Between you and the woman, And between your seed and her Seed; He shall bruise your head, And you shall bruise His heel.” (Genesis 3:15)
These words spoken by the Lord to Satan form the very first prophecy of Jesus Christ, the Messiah. One day, He would come into the world and bruise the head of the serpent (i.e., Satan). Yet Satan would also “bruise His heel.”
What does this mean?
“Theologians have known these key verses since the time when the Scriptures could only be read in Hebrew, Greek, and Latin as the “protoevangelium,” or the first gospel. Perhaps you ask, how did the devil bruise His heel? It may have been the natural result of crucifixion. As a crucifixion victim fights for air, he is forced to push up on his feet so that he can take each breath. That means pushing his full weight upward with one heel, as His feet were nailed together. Because a crucifixion victim had one heel pushed into the cross, that one heel—not both heels, interestingly—would bear a tremendous amount of weight and was, thus, badly bruised.” (Joseph Farah, The Gospel in Every Book Of The Old Testament, 24 (Kindle Edition); Washington, D.C.; WND Books)
What a powerful example of the truthfulness of the Good News of Jesus Christ. The stunning prophecy of Genesis 3:15 pointed inexplicably to the terrible death of the Lord in our place.
