How do we know that Jesus' death was sufficient for our sins?

The sufficiency of Christ's death is affirmed in Scripture, indicating that His sacrifice was complete and effective for those He came to save. Hebrews 10:14 states, 'For by a single offering he has perfected for all time those who are being sanctified.' This means that Jesus' death met every requirement of God's holy law, satisfying divine justice and allowing for the complete forgiveness of sins for His people. The resurrection of Christ is also a crucial affirmation of the efficacy of His sacrifice, as it demonstrated His victory over sin and death and assured believers of their justification before God.
