The teaching of this lesson may be begun with Acts 2:17-21. Surely the outpouring of the Spirit on the day of Pentecost was something new. Yet even that was explained by a reference to prophecy. And the reference is of remarkable aptness and beauty.
The Pentecostal speech of Peter is full of the appeal to prophecy. Primarily, indeed, the claims of Jesus are supported by the direct testimony to his resurrection. Without the facts, of course appeal to prophecy would have been useless; for it was just the wonderful correspondence of the facts with the prophecies that could induce belief. Along with the direct testimony to the facts went the appeal to prophecy. The promised king of David's line at last has come. Acts 2:30; II Sam. 7:12,13; Ps. 89:3,4; 132:11. And David's son is David's Lord—David's Lord and ours. Acts 2:34,35; Ps. 110:1; compare Matt. 22:41-46.
1. THE NEW TESTAMENT APPEAL TO PROPHECY
This speech of Peter is typical of the preaching of the early Church. The appeal to prophecy was absolutely central in the presentation of the gospel. Proof of that fact does not need to be sought. It is written plain on the pages of the New Testament. Old Testament prophecy was found to apply not merely to one side of the work of Christ, but to all sides. Israel had looked not merely for a king, but also for a prophet and a priest. Peter, after his first arrest, for example, could appeal to the notable prophecy of Deuteronomy: "A prophet shall the Lord God raise up unto you from among your brethren, like unto me." Acts 3:22; Deut. 18:15,19. The author of Hebrews could appeal to the priest after the order of Melchizedek, Heb. 5:6; Ps. 110:4, and to the symbolic sacrifices of the temple which found their fulfillment on Calvary.
The appeal to prophecy extended even to those things which were most distinctive of the Christian message. "I delivered unto you first of all," says Paul, "that which also I received: that Christ died for our sins according to the scriptures; and that he was buried; and that he hath been raised on the third day according to the scriptures." I Cor. 15:3,4. Here the death and the resurrection of Christ are both declared to be according to the Scriptures. That means that they were the subject of prophecy. But the death and the resurrection of Christ were the fundamental elements of the gospel. The gospel, then, in the form of prophecy, is to be found in the Old Testament.
What Old Testament passages has Paul here in mind? With regard to the death for our sins, the fifty-third chapter of Isaiah was probably in his mind. That passage was being read by the Ethiopian when Philip met him, and Philip made the passage a basis for preaching about Jesus. Acts 8:27-35. With regard to the resurrection, it is natural to think of Ps. 16:10. Paul himself quoted that passage in his speech at Pisidian Antioch. Acts 13:34-37.
The appeal to prophecy did not begin with the apostles. It was initiated by Jesus himself. "To-day," said Jesus at Nazareth after the reading of Isa. 61:1,2, "hath this scripture been fulfilled in your ears." A large claim! No wonder they found it difficult to accept. When John the Baptist asked, "Art thou he that cometh, or look we for another?" it was to "the works of the Christ" that Jesus appealed. Matt. 11:2-6; Isa. 35:5,6; 61:1. These are merely examples. Throughout, Jesus represented himself and his kingdom as the fulfillment of the ancient promise. "O foolish men," he said to the disciples on the way to Emmaus, "and slow of heart to believe in all that the prophets have spoken! Behooved it not the Christ to suffer these things, and to enter into his glory? And beginning from Moses and from all the prophets, he interpreted to them in all the scriptures the things concerning himself." Luke 24:25-27.
2. THE MESSIANIC HOPE A PREPARATION FOR THE GOSPEL
When the gospel was preached to pure Gentiles, a great deal of preliminary labor had to be done. Under what title should the claims of the Saviour be presented? "Christ" to the Gentiles was almost meaningless, till explained. "Son of God" was open to sad misconception. There were "sons of God" in Greek mythology, but they were not what the early Christians meant to show that Jesus was. These difficulties were overcome, and speedily. Gentile Christians were imbued with a lofty and adequate conception of the Lord. The labor was great, but it was gloriously accomplished.
In this labor, however, the missionaries were assisted by the synagogues of the Jews. In the synagogues, "Christ" was no new term, and no new conception. In the synagogues, one proposition needed first to be proved, "This Jesus ... is the Christ." Acts 17:3. If that were proved, then the rest would follow. The Jews knew that the Messiah was Lord and Master. Identify Jesus with him, and all the lofty claims of Jesus would be substantiated. How the identity was established may be observed in the speech of Peter on the day of Pentecost, or in the speech of Paul at Pisidian Antioch. Acts 13:16-43.
