_Concerning which salvation_, he says, _the prophets sought and searched diligently_. The Divine revelation could only be made as men were able to bear it, and the sentences of old must needs be dark. At first God's love was set forth by His covenants with the patriarchs. Then the wider scope of mercy was proclaimed in the promises given to Abraham and repeated to his posterity. In their seed, it was declared, not the chosen race alone, but all the nations of the earth, should be blessed. Here all through the history was ground enough for diligent searching among the faithful. How could these things be, Abraham solitary and aged, Isaac's sons at feud with each other, Jacob and his posterity in captivity? Even at their best estate these seemed little fitted for the destiny which had been foretold to them. But throughout the Mosaic history some clung to their faith, and their great leader foresaw that the promise would be fulfilled in its time through One of whom he was but a feeble representative. But to so wide a vision only a few attained. In the evil days which followed, the hope of the people must often have dwindled down; but yet at times, as to Gideon's diminished army, it was made manifest that the Lord could do great things for His people: and the thought of the seed of the woman promised as a Deliverer lingered in many hearts, and enabled them to sing in thankfulness how the adversaries of the Lord should be broken in pieces, how out of heaven the Lord should thunder upon them, and prove Himself the Judge of all the ends of the earth, giving strength unto His king and exalting the horn of His anointed. In such wise the prophetic teaching, which had advanced from the blessing of an individual to the choice and exaltation of a chosen family, was expanded in the noblest spirits to the conception of a kingdom of God among all mankind, and assumed a more definite form when the promise was made to the Son of David that His throne should be established for ever. But how imperfectly God's design was comprehended by the best among them we can see from the last words of David himself (2 Sam. xxiii. 1-7). In them we have an instance of the searching which must have occupied other hearts beside that of the king of Israel. The Spirit of the Lord had spoken by him, and a promise of future glory had been made, when all should be brightness, every cloud dispersed. But the vision tarried. The house of David was not so with God. Yet he still held firmly to the everlasting covenant, ordered in all things and sure, a covenant of salvation, though as yet God made it not to grow. David may be numbered among those _who prophesied of the grace that should come_ hereafter; and his words are shaped by a power above his own, to suggest the advent of Him who was to be the "dayspring from on high."
