Why is Christ's sacrifice central to the Christian faith?

The sacrificial death of Christ is the cornerstone of the Christian faith as it embodies God's love and justice. In Mark 12 and throughout the New Testament, Christ is depicted as the Redeemer who; unlike the many sacrifices of the Old Covenant, accomplished a once-for-all offering for sin. He fulfills the law on our behalf and in His resurrection, guarantees new life to all who trust in Him. This centrality emphasizes that salvation is not through our works, but entirely through faith in Christ, who perfectly satisfied God’s justice while demonstrating boundless mercy.
