How do good works relate to our assurance of salvation?

While good works are essential as a demonstration of our faith, they must not be conflated with the basis of our assurance. According to Ephesians 2:10, good works are prepared beforehand so that we may walk in them; they reflect the transformative work of God through His grace. However, our assurance stems from our connection to Christ and the completion of His work for us, as highlighted in Romans 3:20, where our justification is not based on the law or our deeds, but solely upon faith in Jesus. Therefore, while good works are evidence of salvation, they cannot be the foundation upon which our assurance rests.
