forsake Thee, yet will not I,'--and yet he denied Him. Let us take the warning from this venturesomeness of a generous, impulsive, enthusiastic religious nature, and remember that the most genuine faith and religious emotion need to be sobered and steadied by reflection, and by searching into our own motives, before we venture upon the water, howsoever much we may wish to go there. Make very sure that your zeal for the Lord has an element of sober permanence in it, and that it is the result, not of a mere transitory feeling, but of a steady, settled purpose. And do not push yourself voluntarily into places of peril or of difficulty, where the fighting is hard and the fire heavy, unless you have reasonable grounds for believing that you can stand the strain. Bring quiet, sober reason into the loftiest and loveliest enthusiasm of your faith, and then there will be something in it that will live through storm, and walk the water with unwetted and unsinking foot. An impure alloy of selfish itching for pre-eminence and distinction does not seldom mingle with the fine gold of religious enthusiasm and desire to serve and be near our Lord. Therefore we have to test our motives and seek to refine our purest emotions, and the more scrupulously the purer they seem, lest we be yielding to the impulses of self while we fancy that we are being drawn by the magnetism of Christ. II. We have here the momentary triumph and swift collapse of an impure faith. One can fancy with what hushed expectation the other apostles looked at Peter as he let himself down over the side of the ship, and his feet touched the surges and did not sink. Christ's grave, single-worded answer 'Come' barely sanctions the apostle's request. It is at most a permission, but scarcely a command, and it is permission to try, in order that Peter may learn his own weakness. He did walk on the water to go to Jesus. What kept him up? Not Christ's hand, nor any power bestowed on the apostle, but simply the exercise of Christ's will. But if he was held up by the operation of that will, why did he begin to sink? The vivid narrative tells us: 'When he saw the wind boisterous, he was afraid.' That was why. It had been blowing every bit as hard before he stepped out of the ship. The waves were not running any higher after than when he said, 'Bid me come to Thee.' But he was down amongst them, and that makes a wonderful difference. For a moment he stood, and then the peril into which he had so heedlessly thrust himself began to tell on him. Presumption subsided swiftly into fright, as it usually does, and fear began to fulfil itself, as it usually does. 'He became afraid,' and that made him heavy and he began to sink. Not because the gale was any more violent, not because the uneven pavement was any more yielding, but because he was frightened, and his faith began to falter at the close sight of the danger.
