For the intention of all God's hiding--which hiding is an integral part of his revealing--is not to conceal, but to reveal. Sometimes the best way of making a thing known to men is to veil it in a measure, in order that the very obscurity, like the morning mists which prophesy a blazing sun in a clear sky by noonday, may demand search and quicken curiosity and spur to effort. He is not a wise teacher who makes things too easy. It is good that there should be difficulties; for difficulties are like the veins of quartz in the soil, which may turn the edge of the ploughshare or the spade, but prophesy that there is gold there for the man who comes with fitting tools. Wherever, in the broad land of God's word to us, there lie dark places, there are assurances of future illumination. God's hiding is in order to revelation, even as the prophet of old, when he was describing the great Theophany which flashed in light from the one side of the heaven to the other, exclaimed, 'There was the hiding of His power.' 'He hides the purpose of His grace To make it better known.' And the end of all the concealments, and apparent and real obscurities, that hang about His word, is that for many of them patient and diligent attention and docile obedience should unfold them here, and for the rest, 'the day shall declare them.' The lamp is the light for the night-time, and it leaves many a corner in dark shadow; but, when 'night's candles are burnt out, and day sits jocund on the misty mountain-tops,' much will be plain that cannot be made plain now. Therefore, for us the lesson from this assurance that God will not stultify Himself by giving to us a revelation that does not reveal, is, 'Take heed how ye hear.' The effort will not be in vain. Patient attention will ever be rewarded. The desire to learn will not be frustrated. In this school truth lightly won is truth loosely held; and only the attentive scholar is the receptive and retaining disciple. A great man once said, and said, too, presumptuously and proudly, that he had rather have the search after truth than truth. But yet there is a sense in which the saying may be modifiedly accepted; for, precious as is all the revelation of God, not the least precious effect that it is meant to produce upon us is the consciousness that in it there are unscaled heights above, and unplumbed depths beneath, and untraversed spaces all around it; and that for us that Word is like the pillar of cloud and fire that moved before Israel, blends light and darkness with the single office of guidance, and gleams ever before us to draw desires and feet after it. The lamp is set upon a stand. 'Take heed how ye hear.' II. Secondly, the saying, in another application on our Lord's lips, gives us a lesson as to Himself and our attitude to Him.
