'O Thou that earnest from above, The pure celestial fire to impart, Kindle a flame of sacred love On the mean altar of my heart.'
Then there is another thought expressed by this symbol, namely, that this baptism gives cleansing as well as warmth, or rather gives cleansing by warmth. Fire purifies. That Spirit, which is fire, produces holiness in heart and character, by this most chiefly among all His manifold operations, that He excites the flame of love to God, which burns our souls clear with its white fervours. This is the Christian method of making men good,--first, know His love, then believe it, then love Him back again, and then let that genial heat permeate all your life, and it will woo forth everywhere blossoms of beauty and fruits of holiness, that shall clothe the pastures of the wilderness with gladness. Did you ever see a blast-furnace? How long would it take a man, think you, with hammer and chisel, or by chemical means, to get the bits of ore out from the stony matrix? But fling them into the great cylinder, and pile the fire and let the strong draught roar through the burning mass, and by evening you can run off a golden stream of pure and fluid metal, from which all the dross and rubbish is parted, which has been charmed out of all its sullen hardness, and will take the shape of any mould into which you like to run it. The fire has conquered, has melted, has purified. So with us. Love 'shed abroad in our hearts by the Holy Ghost given unto us,' love that answers to Christ's, love that is fixed upon Him who is pure and separate from sinners, will purify us and sever us from our sins. Nothing else will. All other cleansing is superficial, like the water of John's baptism. Moralities and the externals of religion will wash away the foulness which lies on the surface, but stains that have sunk deep into the very substance of the soul, and have dyed every thread in warp and woof to its centre, are not to be got rid of so. The awful words which our great dramatist puts into the mouth of the queenly murderess are heavy with the weight of most solemn truth. After all vain attempts to cleanse away the stains, we, like her, have to say, 'There's the smell of the blood still--will these hands ne'er be clean?' No, never; unless there be something mightier, more inward in its power, than the water with which we can wash them, some better gospel than 'Repent and reform.' God be thanked, there is a mightier detergent than all these--even that divine Spirit which Christ gives, and that divine forgiveness which Christ brings. There, and there alone, dear brethren, we can lose all the guilt of our faultful past, and receive a new and better life which will mould our future into growing likeness to His great purity. Oh do not resist that merciful searching fire, which is ready to penetrate our very bones and marrow, and burn up the seeds of death which lurk in the inmost intents of the heart! Let Him plunge you into that gracious baptism, as we put some poor piece of foul clay into the fire, and like it, as you glow you will whiten, and all the spots will melt away before the conquering tongues of the cleansing flame. In that furnace, heated seven times hotter than any earthly power could achieve, they who walk live by the presence of the Son of Man, and nothing is consumed but the bonds that held them. His Spirit is fire, and that Spirit of fire is, therefore, the Spirit of holiness.
But take one warning word in conclusion. The alternative for every man is to be baptized in the fire or to be consumed by it. The symbol of which we have been speaking sets forth the double thought of purifying and destruction. Nothing which we have said as to the former in the least weakens the completing truth that there is in it an under side of possible terror. One of the felicities of the emblem is its capacity to set forth this twofold idea. There is that in the divine nature which the Bible calls wrath, the necessary displeasure and aversion of holy love from sin and wrong-doers. There is in the divine procedure even now and here, the manifestation of that aversion in punishment. 'The light of Israel becomes a flaming fire.'
