And now a word as to the second of these symbols, Cloven tongues as of fire', the fire of the Spirit.
I need not do more than remind you how frequently that emblem is employed both in the Old and in the New Testament. John the Baptist contrasted the cold negative efficiency of his baptism, which, at its best, was but a baptism of repentance, with the quickening power of the baptism of Him who was to follow him; when he said, I indeed baptise you with water, but He that cometh after me is mightier than I. He shall baptise you with the Holy Ghost and with fire.' The two words mean but one thing, the fire being the emblem of the Spirit.
You will remember, too, how our Lord Himself employs the same metaphor when He speaks about His coming to bring fire on the earth, and His longing to see it kindled into a beneficent blaze. In this connection the fire is a symbol of a quick, triumphant energy, which will transform us into its own likeness. There are two sides to that emblem: one destructive, one creative; one wrathful, one loving. There are the fire of love, and the fire of anger. There is the fire of the sunshine which is the condition of life, as well as the fire of the lightning which burns and consumes. The emblem of fire is selected to express the work of the Spirit of God, by reason of its leaping, triumphant, transforming energy. See, for instance, how, when you kindle a pile of dead green-wood, the tongues of fire spring from point to point until they have conquered the whole mass, and turned it all into a ruddy likeness of the parent flame. And so here, this fire of God, if it fall upon you, will burn up all your coldness, and will make you glow with enthusiasm, working your intellectual convictions in fire not in frost, making your creed a living power in your lives, and kindling you into a flame of earnest consecration.
The same idea is expressed by the common phrases of every language. We speak of the fervour of love, the warmth of affection, the blaze of enthusiasm, the fire of emotion, the coldness of indifference. Christians are to be set on fire of God. If the Spirit dwell in us, He will make us fiery like Himself, even as fire turns the wettest green-wood into fire. We have more than enough of cold Christians who are afraid of nothing so much as of being betrayed into warm emotion.
I believe, dear brethren, and I am bound to express the belief, that one of the chief wants of the Christian Church of this generation, the Christian Church of this river of watery First, cleansing, of which I need not say any more, because I have dealt with it in the previous part of my sermon. Then, further, refreshing, and satisfying. Ah! dear brethren, there is only one thing that will slake the immortal thirst in your souls. The world will never do it; love or ambition gratified and wealth possessed, will never do it. You will be as thirsty after you have drunk of these streams as ever you were before. There is one spring of which if a man drink, he shall never thirst' with unsatisfied, painful longings, but shall never cease to thirst with the longing which is blessedness, because it is fruition. Our thirst can be slaked by the deep draught of the river of the Water of Life, which proceeds from the Throne of God and the Lamb.' The Spirit of God, drunk in by my spirit, will still and satisfy my whole nature, and with it I shall be glad. Drink of this. He! every one that thirsteth, come ye to the waters!
The Spirit is not only refreshing and satisfying, but also productive and fertilising. In Eastern lands a rill of water is all that is needed to make the wilderness rejoice. Turn that stream on to the barrenness of your hearts, and fair flowers will grow that would never grow without it. The one means of lofty and fruitful Christian living is a deep, inward possession of the Spirit of God. The one way to fertilise barren souls is to let that stream flood them all over, and then the flush of green will soon come, and that which is else a desert will rejoice and blossom as the rose.'
So this water will cleanse, it will satisfy and refresh, it will be productive and will fertilise, and everything shall live whithersoever that river cometh.'
