How do we know that Christ's righteousness covers our sins?

Believers know that they are covered by Christ's righteousness through the assurance given in Scripture that emphasizes faith in Christ's redemptive work. As expressed in Matthew 22:11-14, only those clothed in the wedding garment, which symbolizes Christ's righteousness, can enter the kingdom of God. This affirmation assures believers that their past, present, and future sins are covered, allowing them to stand before God without condemnation, supported by promises like Romans 8:1 that there is now no condemnation for those who are in Christ Jesus. Thus, faith in Christ’s finished work provides the confidence of being fully accepted by God.
