Now, opinions differ as to what is meant by this fire. Some would have it to mean the glow of love kindled in believing hearts, and others explain it by other human emotions or by the transformation effected in the world by Christ's coming. But while these things are the results of the fire kindled on earth, that fire itself means not these effects, but the cause of them. It is brought before it kindles a flame on earth.
He does not kindle it simply in humanity, but He launches it into the midst of humanity. It is something from above that He flings down upon the earth.
So it is not merely a quickened intelligence, a higher moral life, or any other of the spiritual and religious transformations which are effected in the world by the mission of Christ that is primarily to be kept in view here, but it is the Heaven-sent cause of these transformations and that flame. If we catch the celestial fire, we shall flash and blaze, but the fire which we catch is not originated on earth. In a word it is God's Divine Spirit which Christ came to communicate to the world.
I need not remind you, I suppose, how such an interpretation of the words before us is in entire correspondence with the symbolism both of the Old and New Testament. I do not dwell upon the former at all, and with regard to the latter I need only remind you of the great words by which the Forerunner of the Lord set forth His mighty work, in contrast with the superficial cleansing which John himself had to proclaim. I indeed baptize you with water, but He shall baptize you with the Holy Ghost and with fire.' I need only point to the Pentecost, and the symbol there, of which the central point was the cloven tongues, which symbolised not only the speech which follows from all deep conviction, but the descent from above of the Spirit of God, who is the Spirit of burning, on each bowed and willing head. With these analogies to guide us, I think we shall not go far wrong if we see in the words of my text our Lord's great symbolical promise that the issue of His mission shall be to bring into the heart of the world, so to speak, and to lodge in the midst of humanity which is one great whole, a new divine influence that shall flame and burn through the world.
So, then, my text opens out into thoughts of the many-sided applications of this symbol. What hopes for the world and ourselves are suggested by that fire? Let us stick to the symbol closely, and we shall then best understand the many-sided blessings that flash and coruscate in the gift of the Spirit.
It is the gift of life. No doubt, here and there in Scripture, fire stands for a symbol of destroying power. But that is a less frequent use than that in which it stands as a symbol of life. In a very real sense life is warmth and death is cold. Is not respiration a kind of combustion? Do not physiologists tell us that? Is not the centre of the system and the father of all physical life that great blazing sun which radiates heat? And is not this promise, I will send fire on the earth,' the assurance that into the midst of our death there shall come the quick energy of a living Spirit which shall give us to possess some shadow of the immortal Being from which itself flows?
But, beyond that, there is another great promise here, of a quickening energy. I use the word quickening,' not in the sense of life-giving, but in the sense of stimulating. We talk about the flame of genius,' the fervour of conviction,' about fiery zeal,' about burning earnestness,' and the like; and, conversely, we speak of cold caution,' and chill indifference,' and so on. Fire means love, zeal, swift energy. This, then, is another side of this great promise, that into the torpor of our sluggish lives He is waiting to infuse a swift Spirit that shall make us glow and flame with earnestness, burn with love, aspire with desire, cleave to Him with the fervour of conviction, and be, in some measure, like those mighty spirits that stand before the Throne, the seraphim that burn with adoration and glow with rapture. A fire that shall destroy all our sluggishness, and change it into swift energy of glad obedience, may be kindled in our spirits by the Holy Spirit whom Christ gives.
Still farther, the promise of my text sets forth, not only life-giving and stimulating energy, but purifying power. Fire cleanses, as many an ancient ritual recognised. For instance, the thought that underlay even that savage passing the children through the fire to Moloch' was, that thus passed, humanity was cleansed from its stains. And that is true. Every man must be cleansed, if he is cleansed at all, by the touch of fire. If you take a piece of foul clay, and push it into a furnace, as it warms it whitens, and you can see the stains melting off it as the fire exercises its beneficent and purifying mastery. So the promise to us is of a great Spirit that will come, and by communicating His warmth will dissipate our foulness, and the sins that are enwrought into the substance of our natures will exhale from the heated surface, and disappear. The ore is flung into the blast furnace, and the scum rises to the surface, and may be ladled off, and the pure stream, cleansed because it is heated, flows out without scoriae or ash. All that was fuel for the fire' is burned; and what remains is more truly itself and more precious. And so, brother, you and I have, for our hope ofcleansing, that we shall be passed through the fire, and dwell in the everlasting burnings of a Divine Spirit and a changeless love.
The last thought suggested by the metaphor is that it promises not only life-giving, stimulating, purifying, but also transforming and assimilating energy. For every lump of coal in your scuttles may be a parable; black and heavy, it is cast into the fire, and there it is turned into the likeness of the flame which it catches and itself begins to glow, and redden, and crackle, and break into a blaze. That is like what you and I may experience if we will. The incense rises in smoke to the heavens when it is heated: and our souls aspire and ascend, an odour of a sweet smell, acceptable to God, when the fire of that Divine Spirit has loosed them from the bonds that bind them to earth, and changed them into His own likeness. We all are changed from glory to glory even as by the Spirit of the Lord.'
So I think if you take these plain teachings of this symbol you learn something of the operations of that Divine Spirit to which our Lord pointed in the great words of my text.
