III. The prophet's commission.--He was not sent on his work with any illusions as to its success, but, on the contrary, he had a clear premonition that its effect would be to deepen the spiritual deafness and blindness of the nation. We must remember that in Scripture the certain effect of divine acts is uniformly regarded as a divine design. Israel was so sunk in spiritual deadness that the issue of the prophet's work would only be to immerse the mass of 'this people' farther in it. To some more susceptible souls his message would be a true divine voice, rousing them like a trumpet, and that effect was what God desired; but to the greater number it would deepen their torpor and increase their condemnation. If men love darkness rather than light, the coming of the light works only judgment. Isaiah recoils from the dreary prospect, and feels that this dreadful hardening cannot be God's ultimate purpose for the nation. So he humbly and wistfully asks how long it is to last. The answer is twofold, heavy with a weight of apparently utter ruin in its first part, but disclosing a faint, far-off gleam of hope on its second. Complete destruction, and the casting of Israel out from the land, are to come. But as, though a goodly tree is felled, a stump remains which has vital force (or _substance_) in it, so, even in the utmost apparent desperateness of Israel's state, there will be in it 'the holy seed,' the 'remnant,' the true Israel, from which again the life shall spring, and stem and branches and waving foliage once more grow up. THE EMPTY THRONE FILLED 'In the year that King Uzziah died I saw also the Lord sitting upon a throne, high and lifted up, and His train filled the temple.'--ISAIAH vi. 1.
