Salvation is by grace alone. Paul declares, “By grace you have been saved through faith… it is the gift of God” (Eph. 2:8). Grace means God saves the undeserving, not the worthy. Calvin reminded us that salvation is “solely by the grace of God, through redemption in Christ.” To deny sola gratia is to rob God of His glory. Doctrine safeguards the church by proclaiming that grace alone saves.
