How do we know that Christian grace is sovereign?

Sovereign grace emphasizes that salvation is initiated and completed by God alone. It is God's choice to save, not based on human merit or adherence to the law. The instances in Acts, where the Apostles encounter the pressure to conform to Jewish customs, reaffirm this principle; they remind us that salvation does not hinge on external rituals but on the grace afforded through faith in Christ alone. Believers are called to recognize this fundamental truth and reject any notion that human effort contributes to salvation.
