Christ's atonement is sufficient because it was a once-for-all sacrifice that fully satisfies God's justice and brings reconciliation for His chosen people.
The sufficiency of Christ's atonement is central to the Reformed faith. In Romans 5:11, we learn that through Christ, we receive the atonement, indicating its completeness. The New Testament consistently portrays Jesus' sacrifice as adequate to cover the sins of all those whom the Father has given Him before the foundation of the world. His death on the cross was not merely symbolic; it was an actual transaction that fulfilled God’s justice, satisfying the demands of His holiness. Ephesians 1:7 states that in Him we have redemption through His blood, the forgiveness of sins, which reinforces the belief that His atonement is indeed sufficient and final.
