Why is grace central to salvation?

Ephesians 2:8-9 explains that by grace, we are saved through faith, emphasizing that salvation is a gift from God and cannot be earned through works. This doctrine of grace underscores the belief that God's love and mercy are freely given and not dependent on human effort or merit. It reveals the character of God as one who desires redemption for His people and showcases His sovereignty in salvation. Recognizing grace is crucial for Christians, as it fosters humility, gratitude, and a desire to live a life that honors God out of response to His kindness.
