How do we know the righteousness of Christ is ours?

The righteousness that belongs to Christ becomes ours through faith, as articulated in Romans 3:20-22, which states that no one is justified by the works of the law, but by faith in Jesus Christ. When we believe in Christ, His perfect righteousness is imputed to us, granting us a status of acceptance before God. This imputed righteousness is not based on our performance but solely on the grace of God, who declares us righteous because of Christ's finished work. Additionally, Romans 8:33-34 reinforces this by stating that it is God who justifies, and this justification is secured by Christ's sacrifice and continual intercession for us. Thus, our confidence rests not in ourselves but in Jesus, our righteousness.
