"_I am undone._" He does not say, "Woe is me! I am not what I ought to be." No; he saw deeper than this. He stood revealed in the power of a light which reaches to the most profound depths of the soul and discloses "the thoughts and intents of the heart." Isaiah had never before seen himself in such a light--measured himself by such a rule--weighed himself in such a balance. He now saw himself standing in the presence of Jehovah's throne without any ability whatever to meet the claims of that throne. He "saw Jehovah sitting upon a throne, high and lifted up." He saw himself a helpless, ruined, guilty sinner at an immeasurable distance from that throne and from the blessed One who sat thereon. He heard the cry of the seraphim, "Holy, holy, holy"; and the only response which he could send back from the depths of a broken heart was, "Unclean, unclean, unclean." He beheld a gulf of guilt and uncleanness separating him from Jehovah which no effort of his could ever bridge. Thus it was with him in that solemn moment when he gave forth that cry of a truly convicted soul, "Woe is me!" He was wholly engrossed with one thought, namely, _his own utter ruin_. He felt himself _a lost man_. He thought not of comparing himself with others, nor of seeking out some fellow-sinner worse than he. Ah, no! a divinely-convicted soul never thinks of such things. There is one grand, all-pervading idea, and that idea is embodied in the words, "I am undone." And be it carefully noted by the reader that the prophet when under the convicting light of the throne is not occupied with what he had done or left undone. The question before his soul was not as to the evil he had done or the good he had left undone. No; it was something far deeper than this. In a word, he was occupied not with his _acts_ but with his _condition_. He says, "_I am_" what? Defective in many things? Far behind in my duty? Deplorably short of what I ought to be? No. These and such-like confessions could never embody the experience of a heart on which the bright beams of Jehovah's throne had fallen in convicting power. True it is "we have done that which we ought not to have done, and left undone that which we ought to have done." But all this is merely the fruit of a nature which is radically corrupt, and when divine light breaks in upon us it will always lead us to the _root_. It will not merely conduct us from leaf to leaf or from branch to branch, but passing down along the trunk it will lay bare the hidden roots of that nature which we inherit by birth from our first parents, and cause us to see that the whole thing is irremediably ruined. Then it is we are constrained to cry out, "Woe is me!" Not because my _conduct_ has been defective, but my nature is undone.
