It was this surrender and subordination of intellect and genius to the divine and spiritual forces which made Paul peerless among the apostles. It was this which gave Wesley his power and radicated his labors in the history of humanity. This gave to Loyola the strength to arrest the retreating forces of Catholicism.
Our great need is heart-preparation. Luther held it as an axiom: “He who has prayed well has studied well.” We do not say that men are not to think and use their intellects; but he will use his intellect best who cultivates his heart most. We do not say that preachers should not be students; but we do say that their great study should be the Bible, and he studies the Bible best who has kept his heart with diligence. We do not say that the preacher should not know men, but he will be the greater adept in human nature who has fathomed the depths and intricacies of his own heart. We do say that while the channel of preaching is the mind, its fountain is the heart; you may broaden and deepen the channel, but if you do not look well to the purity and depth of the fountain, you will have a dry or polluted channel. We do say that almost any man of common intelligence has sense enough to preach the gospel, but very few have grace enough to do so. We do say that he who has struggled with his own heart and conquered it; who has taught it humility, faith, love, truth, mercy, sympathy, courage; who can pour the rich treasures of the heart thus trained, through a manly intellect, all surcharged with the power of the gospel on the consciences of his hearers--such a one will be the truest, most successful preacher in the esteem of his Lord.
