The sermon, rooted in Romans 1:16–17, presents the gospel of Jesus Christ as the transformative power that changes individuals and nations by revealing God's righteousness through faith, not works. It establishes that humanity's fundamental problem is sin—marked by the suppression of truth and the worship of self—leading to divine wrath, yet the gospel offers salvation through Christ's substitutionary death and imputed righteousness, making forgiveness and eternal life possible for all who believe. The preacher emphasizes that true faith involves a radical surrender to Christ, resulting in a transformed life marked by repentance and obedience, and underscores the scandalous grace of God, who can forgive even the most heinous sinners, as exemplified by the Apostle Paul's own redemption. Ultimately, the message calls listeners to confront their own sinfulness, reject self-reliance, and embrace the free gift of salvation through faith in Christ, which alone satisfies both God's justice and His love.
