Why is it significant that Adam and Eve believed in God's promise?

The significance of Adam and Eve's belief lies in their acknowledgment of God's mercy and promise in the midst of their sin. In Genesis 3:15, God proclaimed, 'And 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.' This promise of a coming Savior illustrates the covenant of grace initiated by God even after the fall. By believing in this promise, Adam and Eve demonstrated faith in God's provision for salvation—evidence of divine mercy that extends hope to humanity generations later. Their faith parallels the faith that believers today must exercise in Christ, emphasizing that from the very beginning, salvation has always been through faith in God's revelations.
