Repent Therefore and be Converted

Richard AltmanSun, Apr 12, 2026 · Acts 3:17-26

Summary

The sermon, drawn from Acts 3, centers on the transformative power of repentance as the essential first step in responding to the gospel, rooted in the miraculous healing of a lame man and Peter's bold yet compassionate proclamation to the Jewish leaders who had crucified Christ. It emphasizes that while God's sovereignty fulfilled the Old Testament prophecies of Christ's suffering, the response of the hearers must be genuine repentance—defined not merely as regret but as godly sorrow leading to salvation, a gift of grace that reorients the heart toward God. The message underscores that true repentance results in the blotting out of sins, restoration of fellowship with God, and the promise of spiritual refreshment and eternal hope, all grounded in Christ's atoning work. While affirming the joy and mercy of God, the sermon also issues a sobering warning: rejecting Christ's authority carries eternal consequences, underscoring that repentance is not a one-time event but a continual posture of humility before a holy God. Ultimately, the sermon calls listeners—both unconverted and believers—to embrace repentance as the pathway to renewed life, divine restoration, and intimate communion with God.
