Acts 2:29

Brethren, I may say unto you freely of the patriarch David, that he both died and was buried, and his tomb is with us unto this day. Being therefore a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins he would set one upon his throne; he foreseeing this spake of the resurrection of the Christ, that neither was he left unto Hades, nor did his flesh see corruption.

Peter here affirmed that not only was David fully aware that the promise in his Psalm was not to be fulfilled in himself, but that he also foresaw the resurrection of the Holy One. The certainty of this lies in the words HOLY ONE, there having been utterly no way that David would ever have referred to himself in those words. The memory of Uriah and Bathsheba would never have allowed it.

Implicit in Peter's works is also the fact of David's realization that his throne was to be occupied by that same Holy One, even Christ, who true enough would be the "fruit of" David's body, but in only one dimension, that of the flesh. We need not speculate upon the extent of David's understanding of Christ and his kingdom; but the fact of his being a prophet of God indicates that it was broader and deeper than many suppose.

Resurrection of the Christ ... The significance of "the Christ" should not be overlooked. Jesus was not A Christ, or A Messiah. Jesus of Nazareth is THE Messiah, THE Christ of God! As Alexander Campbell observed:

To maintain this was the main drift of all apostolic preaching and teaching. So important is it, then, that it should stand before all men in the proper attitude. In reading the five historical books of the Christian religion, every intelligent reader must have observed that the issue concerning Jesus of Nazareth is: "Is he, or is he not, the Christ of whom Moses in the law, and all the prophets wrote?"[34]
