It is man’s business to pray; and it takes manly men [1] to do it. It is godly business to pray and it takes godly men to do it. And it is godly men who give over themselves entirely to prayer. Prayer is far-reaching in its influence and in its gracious effects. It is intense and profound business which deals with God and His plans and purposes, and it takes whole-hearted men to do it. No half-hearted, half-brained, half-spirited effort will do for this serious, all-important, heavenly business. The whole heart, the whole brain, the whole spirit, must be in the matter of praying, which is so mightily to affect the characters and destinies of men. – E. M. Bounds, Essentials of Prayer
