How do we know that God is sovereign over salvation?

The doctrine of God's sovereignty in salvation is foundational to Reformed theology, articulated through the concept of effectual calling. Romans 8:30 states that those God predestines, He also calls and justifies, indicating that God's decree is unalterable. Paul discusses his own experience of being called by grace (Galatians 1:15), portraying the initiative of God in the salvation process. Sovereignty means that salvation is not dependent on human will or effort, but on God's merciful choice, as seen in Ephesians 1:4-5 where believers are chosen 'in him before the foundation of the world.' This assurance calls us to cherish God's sovereignty, underscoring that it is He who fulfills His purposes in saving a people for Himself.
