How do we know Christ's death was an accomplishment?

The sermon illustrates that Christ's death should be viewed as an accomplishment, not a failure. In Luke 9:31, Moses and Elijah spoke of the decease He would accomplish at Jerusalem, emphasizing that His death was not merely a tragic event but a purposeful act that secured the redemption of God's chosen people. Various scriptures affirm this perspective, stating that His death did not happen to Him as a failure but was a deliberate action through which He purged sins and established eternal redemption. The concept of Christ's death as an accomplishment is fundamental to sovereign grace theology, reinforcing that salvation is effectually completed through His work, not left to human effort.
