How does God's sovereign grace work in salvation?

God's sovereign grace is evident in salvation through His unconditional choice of whom to save. In Acts 9, God chooses Saul to become one of His vessels, demonstrating that grace is not based on human merit or decision. This sovereign nature ensures that salvation is not dependent on our abilities but is secured by God's power and purpose. This gives believers assurance that their salvation is not merely a momentary decision but a divine work established by God in eternity, highlighting that salvation belongs to the Lord (Psalm 3:8).
