Justification means we are not condemned for our sins. Based upon faith alone in Christ, sinners are justified before God. His sinless life and substitutionary death on the cross for sinners is the basis for our justification. Be justified by faith, through the redemption that is in Christ Jesus (Romans 3:24).
Be justified by faith alone in Christ. Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ (Romans 5:1). Faith is trust and confidence, relying upon Christ alone. By faith in Christ, sinners are justified with God.
Be justified by grace alone through faith in Christ. Faith receives the grace of God in Christ. Faith is the evidence that the believer is justified before God. It is the assurance of faith. Therefore it is of faith that it might be according to grace, so that the promise might be sure to all the seed (Romans 4:16).
Be justified by faith in Christ alone unto righteousness. The only way a sinner can become righteous before God is by faith alone in Christ. Righteousness is the gift of God to us. But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness (Romans 4:5).
