How do we know that God's grace delivers us from sin?

The assurance of God's grace in delivering us from sin is rooted in His sovereign work in our hearts. Ephesians 2:8-9 illustrates that we are saved by grace through faith, not by our works, highlighting that it is God's unmerited favor that causes us to recognize our sinful state and to desire righteousness. As believers, we can be confident that God will work in us 'to will and to act in order to fulfill his good purpose' (Philippians 2:13), guiding us away from sin's dominion and enabling us to bear fruit in alignment with His will. This transformation reflects the true evidence of regeneration and sanctification at work in our lives.
