How do we know that grace is sufficient for our sins?

Ephesians 2:8-9 states, 'For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.' This emphasizes that salvation and justification are based solely on God's grace and not on human effort. The grace of God not only regenerates and justifies His people but sustains them throughout their Christian walk, enabling them to overcome sin. In Romans 8:33-34, Paul poses the rhetorical question of who can bring a charge against God’s elect, affirming that it is God who justifies. Thus, God's grace is not just sufficient; it is the means through which we are made right with Him.
