Ahaz by his wilfulness has made a Substitute necessary. But Isaiah is far more taken up with this: that he has actually mortgaged the prospects of that Substitute. The Messiah comes, but the wilfulness of Ahaz has rendered His reign impossible. He, whose advent has hitherto not been foretold except as the beginning of an era of prosperity, and whose person has not been painted but with honour and power, is represented as a helpless and innocent Sufferer--His prospects dissipated by the sins of others, and Himself born only to share His people's indigence (p. 115). Such a representation of the Hero's fate is of the very highest interest. We are accustomed to associate the conception of a suffering Messiah only with a much later development of prophecy, when Israel went into exile; but the conception meets us already here. It is another proof that _Esaias is very bold_. He calls his Messiah Immanuel, and yet dares to present Him as nothing but a Sufferer--a Sufferer for the sins of others. Born only to suffer with His people, who should have inherited their throne--that is Isaiah's first doctrine of the Messiah. Through the rest of the prophecies published during the Syro-Ephraitic troubles the Sufferer is slowly transformed into a Deliverer. The stages of this transformation are obscure. In chap. viii. Immanuel is no more defined than in chap. vii. He is still only a Name of hope upon an unbroken prospect of devastation. _The stretching out of his wings_--_i.e._, the floods of the Assyrian--_shall fill the breadth of Thy land, O Immanuel_. But this time that the prophet utters the Name, he feels inspired by new courage. He grasps at Immanuel as the pledge of ultimate salvation. Let the enemies of Judah work their worst; it shall be in vain, _for Immanuel, God is with us_. And then, to our astonishment, while Isaiah is telling us how he arrived at the convictions embodied in this Name, the personality of Immanuel fades away altogether, and Jehovah of hosts Himself is set forth as the sole sanctuary of those who fear Him. There is indeed a double displacement here. Immanuel dissolves in two directions. As a Refuge, He is displaced by Jehovah; as a Sufferer and a Symbol of the sufferings of the land, by a little community of disciples, the first embodiment of the Church, who now, with Isaiah, can do nothing except wait for the Lord (pp. 124-126).
