How do we know grace is sufficient for our salvation?

The sufficiency of grace in salvation is a foundational doctrine in Reformed theology, reflecting the belief that God's grace is adequate to cover all human sin. 2 Corinthians 12:9 illustrates this truth, where the Apostle Paul recounts God's reassurance that His grace is sufficient in weakness. The grace of God operates effectively in the lives of believers, not only in their initial redemption but throughout their Christian journey. Romans 5:20 reinforces this idea, stating that where sin abounded, grace abounded much more. This assurance of grace fuels believers' faith and confirms their standing before God, independent of their own works or righteousness.
