How do we know that grace is always saving?

The saving nature of grace is substantiated in Ephesians 2:8, which states, 'For by grace are ye saved through faith; and that not of yourselves: it is the gift of God.' This affirms that salvation is a divine act of grace rather than human merit. Faith itself is a gift from God that enables us to trust in Christ for our salvation, as Romans 10:17 explains that faith comes by hearing the Word of God. Therefore, grace is not merely an offer but an effective work of God that transforms the hearts of His chosen people, leading them to salvation that they could not achieve on their own.
