19. The second part deals with the resurrection of Christ and its power through faith. This is the goal Paul has in view when he tells them that they have slain the Christ, thus effecting their condemnation by God and forfeiting whatever glory they possessed as Jews, gaining shame and wrath before God in its stead. To be still delivered from such condemnation, and to obtain justification and salvation, as he expresses himself toward the end, it is necessary to hear and believe the word concerning the selfsame Christ. Moreover, inasmuch as they with their leaders have refused to receive and recognize this Messiah when he preached and wrought miracles in person; now, that he is invisible and absent in the body, they are called upon to receive him whom they themselves have crucified unto death, and to believe that he is risen from the dead as Lord over all, according to the testimony of the apostles. The dreams of the past they are now utterly to forsake, and their expectations of a Messiah still to come and elevate them with their Law and manner of worship to fame, riches and position, and to spread abroad their Moses and their priesthood in all the earth. They must now thank God for being placed on the same footing with the gentiles, in that they may come with them to the Word of salvation for the purpose of obtaining God's favor, remission of sins and life eternal. OLD TESTAMENT TESTIMONY. 20. Paul supports his discourse on the resurrection of Christ with many strong Scripture texts. There is no doubt that he dwelt on these at length and preached quite a sermon, which, however, has not been recorded here in full, but only in part. The apostle's purpose was to point us to the Old Testament Scriptures, that we might there make diligent study for ourselves of how forcibly the prophets have spoken concerning Christ, his works and his kingdom. 21. The first text Paul cites is from the Second Psalm, which treats throughout of the Messiah and his reign, as even the Jews at the time when wisdom still prevailed had to admit. Christ's own words are: "I will tell of the decree: Jehovah said unto me, Thou art my Son; this day have I begotten thee." Paul says he is here quoting from the First Psalm, though in all editions, old and new, this psalm comes second in order.[2] But the apostle does not have reference to the technical arrangement of the psalms in a book, but to the order of his quotations. The thought is: "First, I will prove it from the psalm," or, "First, as written in the psalm." Just as the preacher of today says, "I observe, first," or, "It is written, first, in the psalm," whether the psalm be the first, second, twentieth or thirtieth, he not having reference to the order of the psalm but to the order in which he cites it. [Footnote 2: Since Luther's time this discrepancy has been removed by allowing the change, "second psalm."]
