How do we know Christ's death is sufficient for our sins?

The sufficiency of Christ's death for our sins is established in Scripture, particularly in Hebrews 10:1-4, which states that the law and its sacrifices were merely shadows of the good things to come and could never make the worshipers perfect. Instead, Christ's sacrifice on the cross is the fulfillment of all sacrificial requirements, providing a once-for-all atonement that removes our guilt and the wrath of God from us. Romans 4:7-8 emphasizes this by declaring blessedness for those whose transgressions are forgiven and sins covered, affirming that through Christ, our sins are eternally removed. This comprehensive sacrifice secures our redemption and reconciles us to God.
