It would scarcely be necessary to spend any time in illustrating that truth, but for the strange misapprehension of the words of our text which I believe to be not uncommon. People sometimes read them as if the first portion referred to those who trust in Christ, and who therefore receive the blessings of His sanctifying energy, whilst the latter words, on the other hand, were a threatening against unbelievers. Now, whatever may be the meaning of the emblem in the preceding and subsequent clauses, it can have but one meaning in our text itself--and that is, the purifying influence of the Spirit of God. Baptism with the Holy Ghost is not one thing and baptism with fire another, but the former is the reality of which the latter is the symbol.
It may be worth while to dwell briefly on the force of the emblem, which is often misunderstood. Fire, then, all over the world has been taken to represent the divine energy. Even in heathendom, side by side with the worship of light was the worship of fire. Even that cruel Moloch-worship, with all its abominations, rested upon the notion that the swift power and ruddy blaze of fire were symbols of glorious attributes. Though the thought was darkened and marred, wrongly apprehended and ferociously worked out in ritual, it was a true thought for all that. And Scripture has from the beginning used it. It would carry us too far to enumerate the instances which might be adduced. But we may quote a few. When the covenant was made between God and Abraham, upon which all the subsequent revelation reposed, the divine presence was represented by a smoking furnace, and a lamp of fire that passed between the divided pieces of the sacrifice. When the great revelation of the divine Name was given to Moses, which prepared for the great deliverance from Egypt, the sign of it was a thorn-bush--one of the many dotted over the desert--burning and unconsumed. Surely the ordinary interpretation, which sees, in that undying flame, an emblem of Israel undestroyed in the furnace of bondage, is less natural than that which sees in it a sign having the same purpose and the same meaning as the deep words, I am that I am.' The Name, the revelation proper, is accompanied by the sign which expresses in figure the very same truths the unwearied power, the undecaying life of the great self-existent God, who wills and does not change, who acts and does not faint, who gives and is none the poorer, who fills the universe and is Himself the same, who burns and is not consumed--the I am.' Further, we remember how to Israel the pledge and sacramental seal of God's guardianship and guidance was the pillar which, in the fervid light of the noonday sun, seemed to be but a column of wavering smoke, but which, when the darkness fell, glowed at the heart and blazed across the sleeping camp, a fiery guard. Who among us,' says the prophet, shall dwell with everlasting burnings?' The answer is a parallel to the description given in one of the Psalms in reply to the question, Lord, who shall abide in Thy tabernacle?' From which parallelism, as well as from the whole tone of the passage, the conclusion is unavoidable that to Isaiah everlasting burnings' was a symbolic designation of God. And, passing by all other references, we remember that our Lord Himself used the same emblem, as John does, with apparently the same meaning, when, yearning for the fulfilment of His work, He said,' I am come to send fire on earth --oh that it were already kindled!' The day of Pentecost teaches the same lesson by its fiery tongues; and the Seer in Patmos beheld, burning before the throne, the sevenfold lamps of fire which are the seven spirits of God.'
Thus, then, there is a continuous chain of symbolism according to which some aspect of the divine nature, and especially of the Spirit of God, is set forth for us by fire. The question, then, comes to be--what is that aspect? In answer, I would remind you that the attributes and offices of the Spirit of God are never in Scripture represented as being destructive, and are only punitive, in so far as the convictions of sin, which He works in the heart, may be regarded as being punishments. The fire of God's Spirit, at all events, is not a wrathful energy, working pain and death, but a merciful omnipotence, bringing light and joy and peace. The Spirit which is fire is a Spirit which giveth life. So the symbol, in the special reference in the text, has nothing of terror or destruction but is full of hope and bright with promise.
Even in its more general application to the divine nature, the same thing is to a large extent true. The common impression is the reverse of this. The interpretation which most readers unconsciously supply to the passages of Scripture where God is spoken of as flaming fire, is that God's terrible wrath is revealed in them. I am very far from denying that the punitive and destructive side of the divine character is in the symbol, but certainly that is not its exclusive meaning, nor does it seem to me to be its principal one. The emblem is employed over and over again, in connections where it must mean chiefly the blessed and joyous aspect of God's Name to men. It is unquestionably part of the felicity of the symbol that there should be in it this double force--for so is it the fitter to show forth Him who, by the very same attributes, is the life of those who love Him and the death of those who turn from Him. But, still, though it is true that the bright and the awful aspects of that Name are in themselves one, and that their difference arises from the difference of the eyes which behold them, yet we are justified, I think, in saying that this emblem of fire regards mainly the former of these and not the latter. The principal ideas in it seem to be swift energy and penetrating power, which cleanses and transforms. It is fire as the source of light and heat; it is fire, not so much as burning up what it seizes into ashes, but rather as laying hold upon cold dead matter, making it sparkle and blaze, and turning it into the likeness of its own leaping brightness; it is fire as springing heavenwards, and bearing up earthly particles in its shooting spires; it is fire, as least gross of visible things;--in a word, it is fire as life, and not as death, that is the symbol of God. It speaks of the might of His transforming power, the melting, Cleansing, vitalising influence of His communicated grace, the warmth of His conquering love. It has, indeed, an under side of possible judgment, punishment, and destruction, but it has a face of blessing, of life-giving, of sanctifying power. And therefore the Baptist spake glad tidings when he said, He shall baptize you with the Holy Ghost, and with fire.'
