Charles H. Spurgeon on Psalms 119:147

I prevented the dawning of the morning, etc. Those that make a business of prayer will use great vigilance and diligence therein. I say, that make a business of prayer; others that use it as a compliment and customary formality, will not be thus affected; they do it as a thing by-the-by, or a work that might well be spared, and do not look upon it as a necessary duty; but if a man's heart be in it, he will be early at work, and follow it close, morning and night: his business is to maintain communion with God, his desires will not let him sleep, and he gets up early to be calling upon God. "But unto thee have I cried, O Lord: and in the morning shall my prayer prevent thee." Psalms 88:13. Thus will good men even break their sleep to give themselves to prayer, and calling upon the name of God. Thomas Manton.
