This brings us to the final aspect of Christ's fulfillment of all sacrifice: His death confirms and enacts a testament. It is no accident that Jesus offered himself up on Golgotha which is a hillock in the vicinity of Mt. Moriah where both the Abrahmic (Gen 22) and the Davidic (2 Sam 24) covenants were confirmed by sacrifice. Both acts of sacrifice prefigured Christ in different ways. In the first case, a father offered up his only son, whereas in the second a king offered himself up for the salvation of his people. Jesus is both the true Son of the Father and the true king of Israel. Also, in both cases, a substitute saved the originally intended victim. Christ fulfilled all these types in his substitutionary sacrifice on the altar of the cross. By his death he also fulfills the promises of universal dominion to a son of David and of universal blessing to all nations present in both the Abrahmic and Davidic covenants, which themselves are restatements and continuations of the protevangelium. The new testament of forgiveness could not come about except for Christ's substitutionary death. As book of Revelation makes clear, it is only because of his death that the "lamb slain from the foundation of the world" (1 Pt 1:18-20, Rev 13:8) is worthy to open the book of the testament (Rev 5:4-11). We find a similar witness in Paul (Gal 4:15). The author of Hebrews agrees and writes: "For a will takes effect only at death, since it is not in force as long as the one who made it is alive"(Heb 9:17).
