How do we know that salvation is not through works?
Answered in 3 sources
Salvation is not through works because grace cannot coexist with the law’s demands for righteousness, as stated in Galatians 2:21.
Scripture consistently teaches that salvation is a gift of grace, not something earned by our works. In Galatians 2:21, Paul states, 'I do not frustrate the grace of God; for if righteousness come by the law, then Christ is dead in vain.' This highlights that if we could achieve righteousness through works, then Christ’s sacrifice would be unnecessary. Righteousness is granted by faith in Christ, as seen in Romans 1:17: 'For in it the righteousness of God is revealed from faith to faith.' Therefore, salvation involves trusting in Christ's accomplishment rather than our own merits.
