Why is the concept of being saved by grace important for Christians?

The doctrine of salvation by grace is central to the Christian faith because it highlights the unmerited favor of God toward sinners. This concept emphasizes that human beings, by their nature, are incapable of achieving righteousness on their own (Romans 3:10). The story of the thief on the cross exemplifies that even in final moments, true faith can lead to salvation, regardless of the past. It shifts the focus from human effort to God’s grace, fostering humility and reliance on Christ. This understanding reassures believers that their standing before God is based on Christ’s righteousness, not their performance.
