How do we know the sacrifice of Christ is sufficient?
Answered in 1 source
The sufficiency of Christ's sacrifice is affirmed by His declaration that it is finished and by God's acceptance of that sacrifice.
The sufficiency of Christ's sacrifice is a foundational truth in Reformed theology, affirmed by the New Testament’s teaching. Jesus declared 'It is finished' (John 19:30), signifying that the work of redemption was accomplished in Him. The author of Hebrews elaborates the finality and sufficiency of Christ's sacrifice, stating that with His one offering He perfected forever those who are sanctified (Hebrews 10:14). Furthermore, God’s refusal to require further sacrifices (Hebrews 10:18) underscores His acceptance of Christ’s work. Thus, we know that the sacrifice of Christ is not only sufficient but has secured eternal redemption, demonstrating the complete and perfect nature of His atonement.
