How do we know the sacrifice of Christ is sufficient for sin?

We know the sacrifice of Christ is sufficient for sin based on the clear teachings of Scripture. Romans 8:1 proclaims, 'There is therefore now no condemnation to them which are in Christ Jesus.' This verse reassures believers that because of Christ's atoning sacrifice, they are completely absolved of guilt and judgment for their sins. Additionally, the sacrificial role of Christ as depicted in 1 Corinthians 1:30 underscores that He became for us wisdom, righteousness, sanctification, and redemption.

The completeness of Christ's redemptive work is emphasized throughout the New Testament, where His death is portrayed as the fulfillment of the Old Testament sacrificial system. As the Lamb slain from the foundation of the world (Revelation 13:8), His sacrifice is not only historically pivotal but also eternally sufficient for the redemption of His people. Believers can rest assured in the truth that Christ's sacrifice meets the full demands of God's justice, providing perfect reconciliation and peace.
