E. M. Bounds on Prayer

There can be no substitute, no rival for prayer; it stands alone as the great spiritual force, and this force must be imminent and acting. It cannot be dispensed with during one generation, nor held in abeyance for the advance of any great movement—it must be continuous and particular, always, everywhere, and in everything. We cannot run our spiritual operations on the prayers of the past generation. Many persons believe in the efficacy of prayer, but not many pray. Prayer is the easiest and hardest of all things; the simplest and the sublimest; the weakest and the most powerful; its results lie outside the range of human possibilities—they are limited only by the omnipotence of God. ~E. M. Bounds, Purpose in Prayer
