Jesus quoted His own words, which He had inspired His servant David to put into writing a thousand years before this day, when He cried, "My God, My God, why have You forsaken Me?" (Psalm 22:1). By repeating it as He hung on the stake, He declared this prophecy to be fulfilled at that very moment; the absolute peak of the agony that He and His Father had planned and foreknew had arrived. Even in His delirium, the utterances of the Logos were solidly based upon His own Word!
Jesus' Final Human Thoughts (Part Two)
Christ's sacrifice confirming the New Covenant occurred on the anniversary of God's covenantal promise to Abraham—the same day and hour! Its specific timing draws our attention to the “eternal inheritance” promised to Abraham and his spiritual seed. Jesus set the example of when and how He wants us to observe the Passover—at the beginning of the 14th—and then on that afternoon, He shed His blood so that a New Covenant could be made.
This covenant is an outgrowth of the covenant with Abraham, making his “great nation” a reality. It provides for justification on the basis of faith—for Israelite and Gentile alike—and promises eternal life to those who continue to the end in faith. Christ is our Passover, not by lining up with the timing outlined in the instructions given to Israel, but by renewing and advancing the covenant God made with Abraham.
