How do we know that Christ's sufferings were sufficient for atonement?

The theological foundation for Christ’s sufficiency in atonement is anchored in His divine nature and the magnitude of His sacrifice. Romans 11:22 highlights the balance of God's goodness and severity in redemptive history, demonstrating that His justice was satisfied through Christ. The greatness of Christ’s sufferings is emphasized by the vastness of the sin He carried, making the atonement powerful enough to cover the sins of many, as noted in the statement that God’s glory is displayed in saving countless souls who deserved condemnation.
