"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." This was a solemn and soul-subduing sight. It is ever a serious matter for a sinner to find himself standing before the throne of God with the unanswered claims of that throne bearing down upon his conscience. Isaiah found it to be so. The light of the throne revealed to him his true condition. And what was that light? It was the moral glory of Christ, as we read in the Gospel of John, "These things said Esaias, when he saw His glory, and spake of Him" (Chap. xii. 41). Christ is the perfect standard by which every one must be measured. It matters not what I may think of myself, nor yet what others may think about me: the question is, What am I as viewed in the presence of Christ? The law may tell me what I ought to be; conscience may tell me I am not that; but it is only when the bright beams of Christ's moral glory pour themselves around me that I am enabled to form a just estimate of what I am. Then it is that the hidden chambers of my heart are laid open, the secret springs of action are revealed, the real condition is laid bare. But perhaps my reader may ask, What do you mean by the moral glory of Christ? I mean the light which shone forth from Him in all His ways when He was down here in this dark world. It was this light that detected _man_, that disclosed what he was, that brought to light _all_ that was in him. It was impossible for any one to escape the action of that light. It was a perfect blaze of divine purity, in view of which the seraphim could only cry out, "Holy, holy, holy!" Need we marvel then if when Isaiah saw himself in the light of that glory he cried out, "Woe is me! for I am undone"? Nay; this was the proper utterance of one whose heart had been penetrated to its very centre by a light which makes all things perfectly manifest. We have no reason to suppose that Isaiah was in any respect worse than his neighbors. We are not told that the catalogue of his sins was heavier or darker than that of thousands around him. He may have been to all human appearance just like others. But ah! my reader, only remember, I pray you, where the prophet stood when he exclaimed, "Woe is me!" It was not at the foot of the burning mount when "the ministration of death and condemnation" was given forth amid thunderings and lightnings, blackness, darkness and tempest. It was not there he stood, though even there a Moses had to say, "I exceedingly fear and quake"; but it was in the presence of the glory of Christ, the Lord God of Israel, that our prophet stood when he saw himself to be "unclean" and "undone." Such was his condition when seen in the light which reveals men and things just as they are.
