We know grace is sufficient because the Bible assures us that God's mercy triumphs over judgment, and His grace provides forgiveness through Christ.
The sufficiency of grace is rooted in the character of God, who is rich in mercy and abounding in steadfast love (Ephesians 2:4-5). It is through His grace that we are saved, as Ephesians 2:8-9 states, 'For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.' This demonstrates that our salvation and forgiveness of sins are fully dependent on God's grace and not our works, which guarantees that grace is indeed sufficient for our needs. When we recognize our total depravity and inability to save ourselves, we can appreciate the fullness of grace offered to us in Christ.
