Why is the doctrine of election crucial for understanding salvation?

The doctrine of election reveals that salvation is not based on human merit but on God's sovereign will. As Ephesians 1:4 states, believers are chosen in Christ before the foundation of the world. This underscores the grace of God in selecting a people for Himself, assuring them of their salvation despite their sinful nature. The doctrine emphasizes that God acts in love and mercy towards those He has predestined, granting them faith to believe. Understanding election cultivates assurance and humility in believers, highlighting that salvation is a gift bestowed by God's grace alone.
