He had in the worst sense destroyed a part of God's works, he had introduce sin into the new world, he had stamped the human race with his own image, and gained new forces to promote rebellion and to multiply transgression, and therefore he felt that sort of gladness which a friend can know who bears a hell within him. But now God comes in, takes up the quarrel personally, and causes him to be disgraced on the very battle-field upon which he had gained a temporary success. He tells the dragon that he will undertake to deal with him; this quarrel shall not be between the serpent and man, but between God and the serpent. God saith, in solemn words, "I will put enmity between thee and the woman, between thy seed and her seed," and he promised that there shall rise in fulness of time a champion, who, though he suffer, shall smite in a vital part the power of evil, and bruise the serpent's head. This was the more, it seems to me, a comfortable message of mercy to Adam and Eve, because they would feel sure that the tempter would be punished, and as that punishment would involve blessing for them, the vengeance due to the serpent would be the guarantee of mercy to themselves.
