The world seems wholly divided between force and fear. Isaiah says, It is not true. Faith has her abiding citadel in the midst, a house of God, which neither force can harm nor fear enter.
This then was Isaiah's Interim-Answer to the Nations—Zion at least is secure for the people of Jehovah.
3. Isaiah could not remain content, however, with so narrow an interim-answer: Zion at least is secure, whatever happens to the rest of you. The world was there, and had to be dealt with and accounted for—had even to be saved. As we have already seen, this was the problem of Isaiah's generation; and to have shirked it would have meant the failure of his faith to rank as universal.
Isaiah did not shirk it. He said boldly to his people, and to the nations: "The faith we have covers this vaster life. Jehovah is not only God of Israel. He rules the world." These prophecies to the foreign nations are full of revelations of the sovereignty and providence of God. The Assyrian may seem to be growing in glory; but Jehovah is watching from the heavens, till he be ripe for cutting down (xviii. 4). Egypt's statesmen may be perverse and wilful; but Jehovah of hosts swingeth His hand against the land: they shall tremble and shudder (xix. 16). Egypt shall obey His purposes (17). Confusion may reign for a time, but a signal and a centre shall be lifted up, and the world gather itself in order round the revealed will of God. The audacity of such a claim for his God becomes more striking when we remember that Isaiah's faith was not the faith of a majestic or a conquering people. When he made his claim, Judah was still tributary to Assyria, a petty highland principality, that could not hope to stand by material means against the forces which had thrown down her more powerful neighbours. It was no experience of success, no mere instinct of being on the side of fate, which led Isaiah so resolutely to pronounce that not only should his people be secure, but that his God would vindicate His purposes upon empires like Egypt and Assyria. It was simply his sense that Jehovah was exalted in righteousness. Therefore, while inside Judah only the remnant that took the side of righteousness would be saved, outside Judah wherever there was unrighteousness, it would be rebuked, and wherever righteousness, it would be vindicated. This is the supremacy which Isaiah proclaimed for Jehovah over the whole world.
How spiritual this faith of Isaiah was, is seen from the next step the prophet took. Looking out on the troubled world, he did not merely assert that his God ruled it, but he emphatically said, what was a far more difficult thing to say, that it would all be consciously and willingly God's. God rules this, not to restrain it only, but to make it His own. The knowledge of Him, which is to-day our privilege, shall be to-morrow the blessing of the whole world.
When we point to the Jewish desire, so often expressed in the Old Testament, of making the whole world subject to Jehovah, we are told that it is simply a proof of religious ambition and jealousy. We are told that this wish to convert the world no more stamps the Jewish religion as being a universal, and therefore presumably a Divine, religion than the Mohammedans' zeal to force their tenets on men at the point of the sword is a proof of the truth of Islam.
Now we need not be concerned to defend the Jewish religion in its every particular, even as propounded by an Isaiah. It is an article of the Christian creed that Judaism was a minor and imperfect dispensation, where truth was only half revealed and virtue half developed. But at least let us do the Jewish religion justice; and we shall never do it justice till we pay attention to what its greatest prophets thought of the outside world, how they sympathized with this, and in what way they proposed to make it subject to their own faith.
Firstly then, there is something in the very manner of Isaiah's treatment of foreign nations, which causes the old charges of religious exclusiveness to sink in our throats. Isaiah treats these foreigners at least as men. Take his prophecies on Egypt or on Tyre or on Babylon—nations which were the hereditary enemies of his nation—and you find him speaking of their natural misfortunes, their social decays, their national follies and disasters, with the same pity and with the same purely moral considerations, with which he has treated his own land. When news of those far-away sorrows comes to Jerusalem, it moves this large-hearted prophet to mourning and tears. He breathes out to distant lands elegies as beautiful as he has poured upon Jerusalem. He shows as intelligent an interest in their social evolutions as he does in those of the Jewish State. He gives a picture of the industry and politics of Egypt as careful as his pictures of the fashions and statecraft of Judah. In short, as you read his prophecies upon foreign nations, you perceive that before the eyes of this man humanity, broken and scattered in his days as it was, rose up one great whole, every part of which was subject to the same laws of righteousness, and deserved from the prophet of God the same love and pity. To some few tribes he says decisively that they shall certainly be wiped out, but even them he does not address in contempt or in hatred. The large empire of Egypt, the great commercial power of Tyre, he speaks of in language of respect and admiration; but that does not prevent him from putting the plain issue to them which he put to his own countrymen: If you are unrighteous, intemperate, impure—lying diplomats and dishonest rulers, you shall certainly perish before Assyria. If you are righteous, temperate, pure, if you do trust in truth and God, nothing can move you.
But, secondly, he, who thus treated all nations with the same strict measures of justice and the same fulness of pity with which he treated his own, was surely not far from extending to the world the religious privileges, which he has so frequently identified with Jerusalem. In his old age, at least Isaiah looked forward to the time when the particular religious opportunities of the Jew should be the inheritance of humanity. For their old oppressor Egypt, for their new enemy Assyria, he anticipates the same experience and education, which has made Israel the firstborn of God. Speaking to Egypt, Isaiah concludes a missionary sermon, fit to take its place beside that which Paul uttered on the Areopagus to the younger Greek civilisation, with the words, In that day shall Israel be a third to Egypt and to Assyria, a blessing in the midst of the earth, for that Jehovah of hosts hath blessed them, saying, Blessed be Egypt My people, and Assyria the work of My hands and Israel Mine inheritance.
