How do we know faith is necessary for righteousness?

The necessity of faith for righteousness is emphasized throughout Scripture, particularly in Romans 5, which states, 'being justified by faith, we have peace with God through our Lord Jesus Christ.' Our righteousness does not come from our works or adherence to the law but is solely a gift received by faith in Christ. This justification is confirmed through the resurrection of Jesus, which assures us of our status before God. By faith, we acknowledge our inability to achieve righteousness on our own and rest in Christ's accomplished work.
