From the racial temper of the elect nation we pass to their history, on the singularity of which our prophet dwells with emphasis. Israel's political origin had no other reason than a call to God's service. Other peoples grew, as it were, from the soil; they were the product of a fatherland, a climate, certain physical environments: root them out of these, and, as nations, they ceased to be. But Israel had not been so nursed into nationality on the lap of nature. The captive children of Jacob had sprung into unity and independence as a nation at the special call of God, and to serve His will in the world,--His will that so lay athwart the natural tendencies of the peoples. All down their history it is wonderful to see how it was the conscience of this service, which in periods of progress was the real national genius in Israel, and in times of decay or of political dissolution upheld the assurance of the nation's survival. Whenever a ruler like Ahaz forgot that Israel's imperishableness was bound up with their faithfulness to God's service, and sought to preserve his throne by alliances with the world-powers, then it was that Israel were most in danger of absorption into the world. And, conversely, when disaster came down, and there was no hope in the sky, it was upon the inward sense of their election to the service of God that the prophets rallied the people's faith and assured them of their survival as a nation. They brought to Israel that sovereign message, which renders all who hear it immortal: "God has a service for you to serve upon earth." In the Exile especially, the wonderful survival of the nation, with the subservience of all history to that end, is made to turn on this,--that Israel has a unique purpose to serve. When Jeremiah and Ezekiel seek to assure the captives of their return to the land and of the restoration of the people, they commend so unlikely a promise by reminding them that the nation is the Servant of God. This name, applied by them for the first time to the nation as a whole, they bind up with the national existence. _Fear thou not, O My Servant Jacob, saith Jehovah; neither be dismayed, O Israel: for, lo, I will save thee from afar, and thy seed from the land of their captivity._[143] These words plainly say, that Israel as a nation cannot die, for God has a use for them to serve. The singularity of Israel's redemption from Babylon is due to the singularity of the service that God has for the nation to perform. Our prophet speaks in the same strain: _Thou, Israel, My Servant, Jacob whom I have chosen, seed of Abraham My lover, whom I took hold of from the ends of the earth and its corners_. _I have called thee and said unto thee, My Servant art thou, I have chosen thee and have not cast thee away_ (ch. xli. 8 ff). No one can miss the force of these words. They are the assurance of Israel's miraculous survival, not because he is God's favourite, but because he is God's servant, with a unique work in the world. Many other verses repeat the same truth.[144] They call _Israel the Servant_, and _Jacob the chosen_, of God, in order to persuade the people that they are not forgotten of Him, and that their seed shall live and be blessed. Israel survives because he serves--_Servus servatur._
