Godbey's Commentary on the New Testament
Acts 2:30
“Therefore being a prophet and knowing that God swore to him with an oath that one from the fruit of his loins should sit upon his throne.” Peter uses this testimony of David to prove the kingship of Christ. He was born King of the Jews. Paul says (Romans 2:28-29):
“He is not a Jew as one outwardly, neither is circumcision that it is outward in the flesh; but he is a Jew who is one inwardly and circumcision is that of the heart; in the spirit and not in the letter, whose praise is not of men but of God.”
Hence, you see that Jesus was born King of Saints. When Pilate wrote this superscription on His cross above His head in Hebrew, Greek and Latin, the language of religion, learning and law for everybody to read, “This is the King of the Jews,” he wrote an eternal truth. That was the reason why he could not change it afterwards at the request of the Jews. The word Inri, which you so frequently see above crosses at Roman Catholic grave-yards and other places, is a combination of initials and stands for Jesus Nazarenus, Rex Ioudiourum, “Jesus of Nazareth, King of the Jews.”
David, the brightest type of Christ in the Bible, powerfully symbolizes Him in His regal capacity. As David had two coronations, first, he was crowned king of his own tribe at Hebron, and seven and a half years afterward he was crowned king of all the tribes of Israel at Jerusalem, so Christ in His first advent was crowned King of Saints when He ascended up to heaven, when He comes in His glory He will be crowned King of all the nations upon the face of the earth. David never occupied an earthly throne. His kingdom was the divine theocracy centralized in heaven and overlapping on the earth. God said: “I have found David, the son of Jesse, a man after my own heart, who will do all my wills.” The reason why David was a man after God's own heart was not because he was infallible, for he was not, but because he had one fixed and settled policy and purpose in all his administrations, and that was not to do his own will but the will of God (Acts 12:22). Much has been said about the perpetuity of David's throne; great volumes written in an attempt to substitute other dynasties, even of other nations, in lieu of what is regarded as the forfeited throne of David, and thus fulfill the Scriptures. When we undertake to help out the Bible, we always make a mistake and get into trouble. The Bible, like God, does not need any help. If you will throw away your creeds and part company with the devil, the Bible will do its own talking. Here it is positively specified that Jesus, the lineal descendant of David, was born King of the Jews in David's royal line. To be sure, He never reigned on earth. Instead of crowning Him King they killed Him, but here Peter proves demonstratively that he was crowned in heaven King of the Jews and successor of David to sit upon his throne. The Bible is clear in this succession of David and perpetuity of his kingdom on the mediatorial throne in heaven. As to David's earthly throne, instead of all these efforts to find it perpetuated among the Gentiles, which is utterly chimerical, turn with me to the Jerusalem council of apostles, elders and brothers, highest authority this side of heaven, and you find the matter fully explained and the problem solved. Acts 15:16 : “After these things [i.e., the preaching of the gospel to all the Gentiles in the present dispensation] I will return and build again the dynasty of David or the throne which hath fallen down, and will rebuild the ruins of the same and set it up again.” Here we see positively that the temporal wing of David's throne had an interregnum at the time of Christ and the apostles, which is to continue until the King returns in His glory. Then He is going to rebuild the throne of David, restore his kingdom on the earth, destined, as the same Scripture goes on to say, “to encompass all the nations of the globe.” Hence, we see that David's kingdom in the earth is to have this interregnum, which obtained in the former dispensation and continued to the end of the gospel age.
Therefore it is a great mistake to think we have to find David's kingdom perpetuated in the earth, as this would preclude the interregnum which the Scriptures positively reveal. Hence the conclusion of the problem is the simple fact that Jesus Christ, the lineal Son, royal Heir and Successor of David, was born King, and, though prohibited and crucified on earth, He was crowned King when He ascended into heaven, and actually there sitteth on the throne of David, thus perpetuating his kingdom forever. Since David really had no earthly throne, but as king of the divine theocracy, his throne was in heaven, the capital of his kingdom, while it overlapped down in the earth and gave Israel a prelibation of the blessedness of the heavenly kingdom, of which Jerusalem, in the glory of David and Solomon, proximately symbolize heaven, and David's earthly throne was but the temporal counterpart of the heavenly. Hence the temporary dilapidation of David's earthly throne does not invalidate the eternal perpetuity of his kingdom, realized in the mediatorial administration of Christ in heaven and destined in the coming millennial age, adumbrated in the days of David, to reach down and girdle the globe in the glory of the heavenly kingdom. We find interregnum s in many of the time-honored kingdoms of the earth, such as Rome and Britain; but these interregnum s do not invalidate the perpetuity of these kingdoms. Neither does the interregnum of David's throne on earth invalidate the eternal perpetuity of his kingdom, especially in view of the fact that the heavenly nucleus of that kingdom is literally perpetuated in the glorious reign of King Jesus. The very fact that God said to Jesus on His congratulation and coronation, “Sit thou on my right hand till I make thine enemies thy footstool,” involves the unequivocal promise on the part of the Father to shake down every rival potentate in all the earth, whether political or ecclesiastical. The incarnation of the Holy Ghost on the day of Pentecost was a positive confirmation of the coronation of Christ in heaven, as the law must be fully satisfied before the promised restitution can be consummated in the incarnation of the Holy Ghost, actually restoring the human to full spiritual freedom and ushering in the millennial victory. Of course, Luke here gives us but a brief epitome of Peter's sermon, i. e., the salient points. God in the Abrahamic covenant promised the gift of the Holy Ghost. That covenant must be sealed with the blood of Christ before the Holy Ghost, the Restorer and Comforter, can be given.
