How do we know that the righteous are justified by God?

The righteousness of the believer is established not by their own acts but through faith in Christ Jesus. Romans 3:20-22 declares that no one can be justified by the deeds of the law since all have sinned. Instead, the righteousness of God is manifested through faith in Jesus Christ, thus establishing that true justification comes through grace and divine mercy. Believers are seen as righteous because they are viewed in the light of Christ's atonement, which provides the necessary covering for their sins.
