How does God's grace ensure salvation?

The doctrine of grace is central to understanding how salvation works in Reformed theology. Salvation is a work of God alone; it is not contingent upon human choice. As stated in the sermon, the elect are assured of their salvation because it is God who brings them to Himself. This grace is described in Romans 8:30, affirming that those whom God predestined, He called, justified, and glorified—all actions fully enacted by God’s divine will. Hence, this assures believers that their salvation is not dependent on their abilities or decisions but purely on God’s sovereign and immediate grace.
