Spiritual truth is revealed only to the spiritual mind: "The natural man receiveth not the things of the Spirit of God; . . . neither can he know them, because they are spiritually discerned" (1 Cor. ii. 14). Spiritual susceptibility is the essential condition of apprehending spiritual truth. A soul instinct with Divine life, sensitive to Divine impressions, in sympathy with Divine things--this, and this only, can enter in to a realization of those great truths which constitute the Gospel. Without this the very message the pastor is charged to preach he himself will fail to apprehend. He may, indeed, see the Christian doctrines through the eye of an impassive logic, but such a lifeless intellectualism, even when abstractly correct, has no power. The theology of the pulpit is a theology vitalized by prayer and glowing in the heart as a great, living reality. The hearts of men are most surely moved by living truths vividly realized in the speaker's soul. The love of God in the incarnation and death of His Son, the guilt and danger of the souls of men, the glories of the saved and the miseries of the lost,--these are not matters of cold intellection. To him who lives in the atmosphere of prayer they stand out as vivid realities. Such men, like Paul, "believe, and therefore speak;" and in words of burning fervor they utter these great truths and press them on the souls of men. Payson, on his death-bed, said: "Prayer is the first thing, the second thing, the third thing, necessary for a minister." Whitefield spent hours of each day on his knees with God's Word open before him, and it was from the audience-chamber of heaven he went forth to speak those marvelous words of power which stirred the souls of the multitude. These eternal truths thus passed in him beyond mere intellections; they took possession of the whole man, and he could but speak with tender pathos and holy boldness, as he saw light in God's light, and the spiritual world was thus all ablaze with light around him. Jesus Himself, the Chief Pastor, lived a life of ceaseless prayer. Pressed under the burden of souls, he waked while others slept. Sometimes He spent the whole night in prayer; at others, "rising up a great while before day," He sought communion with the Father. "Cold mountains and the midnight air Witnessed the fervor of His prayer." And if He, the Sinless One, the God-man, must needs thus pray, if prayer was essential even to His inner life and to His power in the work assigned Him, how much great necessity must press on His weak, sinful servants! If communion with God filled so large a place in the life of the Chief Pastor, it surely should not have less place in the life of the under-shepherds.
