Why is grace important in the Christian life?

Grace is significant in the Christian life as it encompasses both the initial act of salvation and the continual sustaining of faith throughout a believer's life. Galatians 5:4 warns that those who seek justification through law fall away from grace, indicating that grace is the means by which we are saved and preserved. Grace assures us that we are not saved by our works or morality but by the sheer unmerited favor of God. Understanding this leads believers to rest in Christ's performance rather than their own, shaping how they grow in faith and serve both God and others.
