How do we know that Christ's sacrifice removes our sins?

The assurance of our sins being removed comes from the perfect sacrifice of Jesus Christ, who, according to Hebrews 10:17, has made a once-for-all offering for sin. This profound truth signifies that through His death, God does not hold our sins against us. The Old Testament prophet Isaiah highlights this point with the promise of coming forgiveness, indicating that our sins are removed 'as far as the east is from the west' (Psalm 103:12). In Christ, we find reconciliation with God, illustrating that He bore our sins and fulfilled divine justice, thus allowing believers to stand justified before a holy God.
