Answer: Can there be conceived a weightier announcement, after sin had entered with death ensuing, than Jehovah Elohim made in pronouncing the curse on the Serpent? “I will put enmity between thy seed and her seed: it shall bruise thy head, and thou shall bruise his heel.” While countless souls are by grace associated for all blessing and triumph with the woman’s seed, One is marked out, on Whom all the blessed of similar seed depend, Who should suffer the deepest anguish, yet live (again, as we can add) to crush him who was the liar and the murderer from the beginning, and all who, refusing grace, perpetuate the enmity of Satan.
