How do we know that justification is through faith in Christ?

The assurance of justification through faith in Christ is rooted in the teachings of Romans. As stated in Romans 3:24, we are 'justified freely by His grace through the redemption that is in Christ Jesus.' This means God declares us righteous, not based on our actions, but based entirely on Christ's sacrificial death and resurrection. Transformatively, Romans 5:1 tells us that 'being justified by faith, we have peace with God through our Lord Jesus Christ.' It is through faith in His blood that we are made right before God, which emphasizes that our inadequacies do not disqualify us from His grace.
