How do we know sovereign grace theology is true?

Sovereign grace theology asserts that God is the ultimate authority in the process of salvation, as evidenced in Scripture. Key passages like Ephesians 2:8-9 highlight that salvation is a gift from God and not based on human effort, thus affirming the central tenet that grace alone is sufficient for salvation. The doctrine of total depravity (the first point of TULIP) establishes the necessity of God's grace as humanity is incapable of coming to God without divine intervention. The historic Reformed understanding holds that God, in His sovereignty, chooses whom He will save, as seen in Romans 8:29-30. This theological framework is not only cohesive but resonates with the biblical narrative of redemption.
