How do we know that Christ's righteousness is sufficient for our acceptance?

The sufficiency of Christ’s righteousness for our acceptance with God is rooted in the nature of Jesus as both fully God and fully man, who perfectly fulfilled the law and offered Himself as the perfect sacrifice. Colossians 2:13 mentions that God forgave our trespasses through Christ, affirming that His sacrifice is enough. Additionally, God's acceptance of Christ at His right hand, as noted in Ephesians 1:20-22, confirms that He is satisfied with Christ’s work on behalf of His people. Thus, when we are in Christ, we are assured of perfect acceptance.
