Within a few years they will certainly be destroyed. But whatever estimate you make of your foes, whatever their future may be, for yourself have faith in God; for you that is the essential thing. _If ye will not believe, surely ye shall not be established._[13] [13] There is a play upon words here, which may be reproduced in English by the help of a North-England term: If ye have not _faith_, ye cannot have _staith_. This paraphrase seeks to bring out the meaning of a passage confessedly obscure. It seems as if we had only bits of Isaiah's speech to Ahaz and must supply the gaps. No one need hesitate, however, to recognize the conspicuous personal qualities--the combination of political sagacity with religious fear, of common-sense and courage rooted in faith. In a word, this is what Isaiah will say to the king, clever in his alliances, religious and secular, and busy about his material defences: "Take unto you the shield of faith. You have lost your head among all these things. Hold it up like a man behind that shield; take a rational view of affairs. Rate your enemies at their proper value. But for this you must believe in God. Faith in Him is the essential condition of a calm mind and a rational appreciation of affairs." It is, no doubt, difficult for us to realize that the truth which Isaiah thus enforced on King Ahaz--the government of the world and human history by one supreme God--was ever a truth of which the race stood in ignorance. A generation like ours cannot be expected to put its mind in the attitude of those of Isaiah's contemporaries who believed in the real existence of many gods with limited sovereignties. To us, who are full of the instincts of Divine Providence and of the presence in history of law and progress, it is extremely hard even to admit the fact--far less fully to realize what it means--that our race had ever to receive these truths as fresh additions to their stock of intellectual ideas. Yet, without prejudice to the claims of earlier prophets, this may be confidently affirmed: that Isaiah where we now meet him stood on one side believing in one supreme God, Lord of heaven and earth, and his generation stood on the other side, believing that there were many gods. Isaiah, however, does not pose as the discoverer of the truth he preaches; he does not present it as a new revelation, nor put it in a formula. He takes it for granted, and proceeds to bring its moral influence to bear. He will infect men with his own utter conviction of it, in order that he may strengthen their character and guide them by paths of safety. His speech to Ahaz is an exhibition of the moral and rational effects of believing in Providence. Ahaz is a sample of the _character_ polytheism produced; the state of mind and heart to which Isaiah exhorts him is that induced by belief in one righteous and almighty God. We can make the contrast clear to ourselves by a very definite figure.
