It is man’s business to pray; and it takes manly men 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
