The central message of this sermon is that humanity's trajectory after the fall is one of decline and failure, despite some rare instances of godliness. The story of Cain and Abel in Genesis 4 illustrates this point, revealing that even from the earliest stages of human history, there has been a fundamental division between those who live in faith and humility, calling on God for salvation, and those who assert their own self-righteousness and independence from God. This dichotomy is reflected in the contrast between Abel's faith and righteousness, which earned him God's favor, and Cain's pride and rebellion, which led to his downfall. The sermon suggests that this struggle between good and evil, or the "seed of the woman" and the "seed of the serpent," will continue throughout human history until its ultimate conclusion in a final judgment between Christ and Antichrist. Ultimately, the takeaway from this sermon is that humanity's natural tendency is towards self-destruction and rebellion against God, but through faith in Christ, we can break free from this trajectory and live a life pleasing to God.
