If we desire to be delivered, let us go into the fire. It will burn up all our evil, and it will burn up nothing else. Keep close to Christ. Lay your hearts open to the hallowing influences of the motives and the examples that lie in the story of His life and death. Seek for the fiery touch of that transforming Spirit, and be sure that you quench Him not, nor grieve Him. And then your weakness will be reinvigorated by celestial powers, and the live coal upon your lips will burn up all your iniquity.
But, subordinately to this deepest meaning, as I take it, of the great symbol of our text, let me remind you of another possible application of it, which follows from the preceding. God's Spirit cleanses men mainly by raising their spirits to a higher temperature. For coldness is akin to sin, and heavenly warmth is akin to righteousness. Enthusiasm always ennobles, delivers men, even on the lower reaches of life and conduct from many a meanness and many a sin. And when it becomes a warmth of spirit kindled by the reception of the fire of God, then it becomes the solvent which breaks the connection between me and my evil. It is the cold Christian who makes no progress in conquering his sin. The one who is filled with the love of God, and has the ardent convictions and the burning enthusiasm which that love ought to produce in our hearts, is the man who will conquer and eject his evils.
Nor must we forget that there is still another possible application of the words. For whilst, on the one hand, the Divine Spirit's method of delivering us is very largely that of imparting to us the warmth of ardent, devout emotion; on the other hand, a part of this method is the passing of us through the fiery trials and outward disciplines of life. 'Every one shall be salted with fire' in that sense. And we have learned, dear brethren, but little of the loving kindness of the Lord if we are not able to say, 'I have grown more in likeness to Jesus Christ by rightly accepted sorrows than by anything besides.' Be not afraid of calamities; be not stumbled by disaster. Take the fiery trial which is sent to you as being intended to bring about, at the last, the discovery 'unto praise and honour and glory' of your faith, that is 'much more precious than gold that perisheth, though it be tried with fire.' 'Every one shall be salted with fire,' the Christian law of life is, Submit to the fiery cleansing. Alas! alas! for the many thousands of professing Christians who are wrapping themselves in such thick folds of non-conducting material that that fiery energy can only play on the surface of their lives, instead of searching them to the depths. Do you see to it, dear brethren, that you lay open your whole natures, down to the very inmost roots, to the penetrating, searching, cleansing power of that Spirit. And let us all go and say to Him, 'Search me, O God! and try me, and see if there be any wicked way in me.'
II. Notice the painfulness of this fiery cleansing.
The same ideas substantially are conveyed in my text as are expressed, in different imagery, by the solemn words that precede it. The 'salting with fire' comes substantially to the same thing as the amputation of the hand and foot, and the plucking out of the eye, that cause to stumble. The metaphor expresses a painful process. It is no pleasant thing to submit the bleeding stump to the actual cautery, and to press it, all sensitive, upon the hot plate that will stop the flow of blood. But such pain of shrinking nerves is to be borne, and to be courted, if we are wise, rather than to carry the hand or the eye that led astray unmutilated into total destruction. Surely that is common sense.
The process is painful because we are weak. The highest ideal of Christian progress would be realised if one of the metaphors with which our Lord expresses it were adequate to cover the whole ground, and we grew as the wheat grows, 'first the blade, then the ear, after that the full corn in the ear.' But the tranquillity of vegetable growth, and the peaceful progress which it symbolises, are not all that you and I have to expect. Emblems of a very different kind have to be associated with that of the quiet serenity of the growing corn, in order to describe all that a Christian man has to experience in the work of becoming like his Master. It is a fight as well as a growth; it is a building requiring our continuity of effort, as well as a growth. There is something to be got rid of as well as much to be appropriated. We do not only need to become better, we need to become less bad. Squatters have camped on the land, and cling to it and hold it vi et armis; and these have to be ejected before peaceful settlement is possible.
One might go on multiplying metaphors ad libitum, in order to bring out the one thought that it needs huge courage to bear being sanctified, or, if you do not like the theological word, to bear being made better. It is no holiday task, and unless we are willing to have a great deal that is against the grain done to us, and in us, and by us, we shall never achieve it. We have to accept the pain. Desires have to be thwarted, and that is not pleasant. Self has to be suppressed, and that is not delightsome. A growing conviction of the depth of one's own evil has to be cherished, and that is not a grateful thought for any of us. Pains external, which are felt by reason of disciplinary sorrows, are not worthy to be named in the same day as those more recondite and inward agonies. But, brother, they are all 'light' as compared with the exceeding weight of 'glory,' coming from conformity to the example of our Master, which they prepare for us.
And so I bring you Christ's message: He will have no man to enlist in His army under false pretences. He will not deceive any of us by telling us that it is all easy work and plain sailing. Salting by fire can never be other than to the worse self an agony, just because it is to the better self a rapture. And so let us make up our minds that no man is taken to heaven in his sleep, and that the road is a rough one, judging from the point of view of flesh and sense; but though rough, narrow, often studded with sharp edges, like the plough coulters that they used to lay in the path in the old rude ordeals, it still leads straight to the goal, and bleeding feet are little to pay for a seat at Christ's right hand.
III. Lastly, notice the preservative result of this painful cleansing.
Our Lord brings together, in our text, as is often His wont, two apparently contradictory ideas, in order, by the paradox, to fix our attention the more vividly upon His words. Fire destroys; salt preserves. They are opposites. But yet the opposites may be united in one mighty reality, a fire which preserves and does not destroy. The deepest truth is that the cleansing fire which the Christ will give us preserves us, because it destroys that which is destroying us. If you kill the germs of putrefaction in a hit of dead flesh, you preserve the flesh; and if you bring to bear upon a man the power which will kill the thing that is killing him, its destructive influence is the condition of its conserving one.
