How do we know that we are saved by grace and not by works?

In Romans 3:20, it states, 'Therefore by the deeds of the law there shall no flesh be justified in his sight.' This underscores the futility of attempting to achieve salvation through our own works or adherence to the law. Salvation is a gift from God, not something we can accomplish on our own. Ephesians 2:9 reiterates this by stating that it is not of works lest any man should boast, reinforcing the idea that our salvation is purely by God’s sovereign grace. This assurance frees us from reliance on our imperfect actions and points us to Christ, the ultimate source of our salvation.
