God said, “I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel” (Gen. 3:15).
 
Is it not amazing that God’s voice should be recorded so early in the Divine record, giving man the assurance that another and better Adam would come and that He would completely triumph over the seed of the serpent?  Only God could include in one very comprehensive statement the entire history of the two Adams.
