How do we know that salvation is not through works?

Salvation as a divine gift rather than a human achievement is a central theme in Scripture, especially articulated in Ephesians 2:8-9, which emphasizes that it is by grace we have been saved, not by works, so that no one can boast. This truth is grounded in the character of God as one who desires to save us through faith alone. The act of Christ’s sacrifice fulfills the law's demands for us, which demonstrates that human works are inadequate for reconciliation with God (Romans 3:28). Ultimately, our hope rests not on what we can do but on the perfect and sufficient work of Christ, which is the heart of the gospel message.
