How do we know Christ's sacrifice is sufficient for redemption?

The sufficiency of Christ's sacrifice for redemption is established through both Scripture and the nature of His sacrifice. In Hebrews 10:14, it is stated that 'by one offering He has perfected forever those who are being sanctified.' This declaration emphasizes the completeness of Christ's work. Because He is both fully God and fully man, His sacrificial death is infinitely valuable, satisfying the justice of God on behalf of all who believe.

Moreover, Christ did not come to offer a temporary fix or an approximation of redemption; He came to achieve a definitive work. Throughout the sermon, it is emphasized that Christ’s offering was a once-for-all event, contrasting with the ongoing sacrifices of the Old Covenant that could never truly cleanse the conscience (Hebrews 10:1-4). The resurrection of Christ is further evidence that His sacrifice was accepted by the Father, showcasing that He not only paid the penalty for sin but also triumphed over death, confirming the efficacy of His redemption for all who trust in Him.
