Ah, Lord God! Behold, You have made the heavens and the earth by Your great power and outstretched arm. There is nothing too hard for You. — Jer. 32:17
When Tennyson wrote "More things are wrought by prayer than this world dreams of," he probably uttered a truth of vaster significance than even he understood. While it is not always possible to trace an act of God to its prayer-cause, it is yet safe to say that prayer is back of everything that God does for the sons of men here upon earth. One would gather as much from a simple reading of the Scriptures.
What profit is there in prayer? "Much every way." Whatever God can do faith can do, and whatever faith can do prayer can do when it is offered in faith. An invitation to prayer is, therefore, an invitation to omnipotence, for prayer engages the Omnipotent God and brings Him into our human affairs. Nothing is impossible to the man who prays in faith, just as nothing is impossible with God. This generation has yet to prove all that prayer can do for believing men and women.
