How does the doctrine of predestination relate to salvation?

Predestination is a core aspect of sovereign grace theology, reflecting God's sovereignty in the act of salvation. Ephesians 1:4-5 reveals that believers were chosen in Christ before the foundation of the world, underscoring that salvation is not a result of human will or effort but rather a divine decision made by God. This doctrine assures Christians that their salvation is secured by God's immutable will, and it highlights the grace of God in acting to save those whom He has chosen. Understanding predestination encourages believers to rest in God's promises and to recognize that salvation is entirely an act of His grace, given freely and unmerited, thus leading to worship and gratitude.
