Holy men of soberer and quieter times than ours knew well the power of silence. David said, I was dumb with silence, I held my peace, even from good; and my sorrow was stirred. My heart was hot within me; while I was musing the fire burned: then spake I with my tongue. There is a tip here for God’s modern prophets. The heart seldom gets hot while the mouth is open. A closed mouth before God and a silent heart are indispensable for the reception of certain kinds of truth. No man is qualified to speak who has not first listened. It might well be a wonderful revelation to some Christians if they were to get completely quiet for a short time, long enough, let us say, to get acquainted with their own souls, and to listen in the silence for the deep voice of the Eternal God. The experience, if repeated often enough, would do more to cure our ulcers than all the pills that ever rolled across a desk.
