Christmas is observed each year by people from many different countries. The great hope of Christmas is summed up in Matthew 1:21—“She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” That is great hope, as the fall of man means that Adam’s descendants fell into sin with him. Paul makes this clear in Romans 5:12-21. If we stand in Adam, we stand without hope.
But Jesus has come to succeed where Adam failed. Jesus is the Second Adam. And as early as Genesis 3:15, that great hope is promised. That verse reads, “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.” This is in the context of the curse placed upon the serpent. There is one who will crush the head of the serpent. That is the promise made here to Adam and to the people of God. Jesus Christ is coming, and though He is the one who will have His heel stricken in His death, He is also the one who will triumph in His death and resurrection. He will crush the head of the serpent.
