Again, note the second stage here, in the education of a soul for service--the sin, recognised and repented, is burned away.
Then flew one of the seraphim unto me, having a live coal in his hand, which he had taken with the tongs from off the altar; and he laid it upon my mouth, and said, Lo! this hath touched thy lips; and thine iniquity is taken away, and thy sin purged.'
Now, I would notice as to this stage of the process, first, that Isaiah singularly passes beyond all the old ritual in which he had been brought up, and recognises another kind of cleansing than that which it embodied. He had got beyond the ritual to what the ritual meant. We have passed beyond the ritual, too, by another process; and, though I would by no means read full, plain, articulate Christian thought into the vision of Isaiah--which would be an anachronism, and unfaithful to the gradual historical development of the idea and means of redemption--yet I cannot help pointing to the fact that, even although this vision is located as seen in the Temple, there is not a single reference (except that passing allusion to the altar) to the ritual of the Temple, but the cleansing comes in another fashion altogether.
But far more important than that thought is the human condition that is required ere this cleansing can be realised. I am a man of unclean lips.' I am undone!' It was because that conviction and confession sprang in the prophet's consciousness that the seraph winged his way with the purifying fire in his hands. Which being translated is just this: faith alone will not bring cleansing. There must go with it what we call, in our Christian phraseology, repentance, which is but the recognition of my own antagonism to the holiness of God, and the resolve to turn my back on my own past self. Now, it seems to me that a great deal of what is called, and in a sense is, Evangelical teaching, fails to represent the full counsel of God, in the matter of man's redemption, because it puts a one-sided emphasis on faith, and slurs over the accompanying idea of repentance. And I am here to say that a trust in Jesus Christ, which is unaccompanied by a profound penitent consciousness and abhorrence of one's own sins, and a resolve to turn away from them for the time to come, is not a faith which will bring either pardon or cleansing. We do not need to have less said about trust; we need to have a great deal more said about repentance. You have to learn what it is to say, I abhor myself'; you have to learn what it is to say, I will turn right round, and leave all that past behind me; and go in the opposite direction'; or the faith which you say you are exercising will neither save nor cleanse your souls nor your lives.
Again, note that we have here set forth most strikingly the other great truth that, side by side, and as closely synchronous as the flash and the peal, as soon as the consciousness of sin and the aversion from it spring in a man's heart, the seraph's wings are set in motion. Remember that beautiful old story in the historical books, of how the erring king, brought to sanity and repentance by Nathan's apologue, put all his acknowledgments in these words, I have sinned against the Lord'; and how the confession was not out of his lips, nor had died in its vibration in the atmosphere, before the prophet, with divine authority, replied with equal brevity and completeness, and as if the two sayings were parts of one sentence, .And the Lord hath made to pass the iniquity of thy sin.' That is all. Simultaneous are the two things. To confess is to be forgiven, and the moment that the consciousness of sin rises in the heart, that moment does the heavenly messenger come to still and soothe.
Still further, notice how the cleansing comes as a divine gift. It is purifying, much more than pardon, that is set forth in the symbolical incident before us. The seraph is the divine messenger, and he brings a coal from the altar, and lays that upon the prophet's lips, which is but the symbolical way of saying that the man who is conscious of his own evil will find in himself a blessed despair of being his own healer, and that he has to turn to the divine source, the vision of which has kindled the consciousness, to find there that which will take away the evil. The Lord is He that healeth us.'
But, further, the cleansing is by fire. By which, as I suppose, in the present context, and at Isaiah's stage of religious knowledge and experience, we are to understand that great thought that God burns away our sins, as you put a piece of foul clay into the fire, and the stain melts from the surface like a dissipating cloud as the heat finds its way into the substance. He will baptize with the Holy Ghost and with fire'--a fire that quickens. A new impulse will be granted, which will become the life of the sinful man's life, and will emancipate him from the power of his own darkness and evil.
Now, let us remember that we have the fulness of all that was shadowed to the prophet in this vision, and that the reality of every one of these emblems is gathered together--if I may so say--not with confusion, but with abundance and opulence in Jesus Christ Himself. Is He not the seraph? Is He not Himself the burning coal? Is He not the altar from which it is taken? All that is needed to make the foulest clean is given in Christ's great work. Brethren, we shall never understand the deepest secret of Christ and of Christianity until we learn and hold fast by the conviction that the central work of Jesus is to deal with man's sin; and that whatever else Christianity is, it is first and foremost God's way of redeeming the world, and making it possible for the unholy to dwell with His holy self.
