How do we know Christ's death is central to Christian faith?

The gospel narrative emphasizes the necessity of Christ's death as the ultimate atonement for sin. In Mark 11, the significance of His public entry into Jerusalem is intertwined with the reality of His impending death. Jesus did not shy away from this reality but openly declared His purpose, knowing that His sacrifice would fulfill the prophecies concerning the Messiah. Without His death, there is no basis for our hope as believers; it is the crowning event that secures our reconciliation with God. Theologically, the doctrine of the atonement asserts that through Christ's death, He bore the penalty for sin, thus offering salvation to all who believe, making it a focal point of the Christian faith.
