God forbid that I should seem to deprecate emotional religion or religious emotion! that is the last thing that needs to be done in this generation. If the Churches want one thing more than another, it is that their Christianity should become far more emotional than it is, and their impulses stronger, swifter, more spontaneous, more overmastering, and that they should be urged by these, and not merely by the reluctant recognition that such and such a piece of sacrifice or effort is a debt that they are obliged to clear off. Their service will be glad service, only when it is impulsive service and emotional service. Dear brethren, a Christian man whose life is not influenced by the deepest and most fervid emotion of love to the great Love that died for him, is a monster. 'The Lord's fire is in Jerusalem, and His furnace in Zion'—is that a description of the fervour of this Church, or of any Church in Christendom? A furnace? An ice-house! Think of some deserted cottage, with the roof fallen in, and in the cold chimney-place a rusty grate with some dead embers in it, and the snow lying upon the top of it—that is a truer description of a great many of our churches than 'the Lord's furnace.'
But the lesson to be taken from this incident before us is not the danger of emotion; it is rather the necessity of emotion, but with two provisoes, that it shall be emotion based upon a clear recognition of the great truth that He has laid down His life for me; and that it shall be emotion harnessed to work, and not wasted in words. The mightier the plunge of the fall, the more electrical energy you can get out of it, and set that to work to drive the wheels of life. Do not be afraid of emotion; you will make little of your Christianity unless you have it. But be sure that it is under the guidance of a clear perception of the truth that evokes it, and that it is all used to turn the wheels of life. 'Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.' Better is it that emotion should be reticent and active than that it should be voluble and idle. It is a good servant, but a bad master. A man that trusts to impulse and emotion to further his Christian course, is like a ship in that belt of variable winds that lies near the Equator, where there will be a fine ten-knot breeze for an hour or two, and then a sickly, stagnating calm. Push further south, and get into the steady 'trades,' where the wind blows with equable and persistent force all the year round in the same direction. Convert impulses and emotions into steadfast principle, warmed by emotion and borne on by impulse.
II. Again, this rash vow is an illustration of a confidence, also strangely blended of good and evil.
'I will lay down my life for Thy sake.' As I have said, Peter meant it. His words are paralleled by other words, in which two of the Lord's disciples answered His solemn question: 'Are ye able to drink of the cup that I drink of?' with the unhesitating answer, 'We are able.' A great teacher has regarded that saying as one of 'the ventures of faith.' Perhaps it was. Perhaps there was as much self-confidence as faith in it. Certainly there was more self-confidence than faith in Peter's answer, and his self-confidence collapsed when the trial came.
The world and the Church hold entirely antagonistic notions about the value of self-reliance. The world says that it is a condition of power. The Church says that it is the root of weakness. Self-confidence shuts a man out from the help of God, and so shuts him out from the source of power. For if you will think for a moment, you will see that the faith which the New Testament, in conformity with all wise knowledge of one's self, preaches as the one secret of power, has for its obverse—its other side—diffidence and self-distrust. No man trusts God as God ought to be trusted, who does not distrust himself as himself ought to be distrusted. To level a mountain is the only way to carry the water across where it stood. You can, by mechanism and locks, take a canal up to the top of a hill, but you cannot take a river up to the top, and the river of God's help flows through the valley and seeks the lowest levels. Faith and self-despair are the upper and the under sides of the same thing, like some cunningly-woven cloth, the one side bearing a different pattern from the other, and yet made of the same yarn, and the same threads passing from the upper to the under sides. So faith and self-distrust are but two names for one composite whole.
