To pray successfully is the first lesson the preacher must learn if he is to preach fruitfully; yet prayer is the hardest thing he will ever be called upon to do and, being human, it is the one act he will be tempted to do less frequently than any other. He must set his heart to conquer by prayer, and that will mean that he must first conquer his own flesh, for it is the flesh that hinders prayer always.
Almost anything associated with the ministry may be learned with an average amount of intelligent application. It is not hard to preach or manage church affairs or pay a social call; weddings and funerals may be conducted smoothly with a little help from Emily Post and the Minister’s Manual. Sermon making can be learned as easily as shoemaking—introduction, conclusion and all. And so with the whole work of the ministry as it is carried on in the average church today.
But prayer—that is another matter. There Mrs. Post is helpless and the Minister’s Manual can offer no assistance. There the lonely man of God must wrestle it out alone, sometimes in fastings and tears and weariness untold. There every man must be an original, for true prayer cannot be imitated nor can it be learned from someone else. Everyone must pray as if he alone could pray, and his approach must be individual and independent; independent, that is, of everyone but the Holy Spirit.
Thomas à Kempis says that the man of God ought to be more at home in his prayer chamber than before the public. It is not too much to say that the preacher who loves to be before the public is hardly prepared spiritually to be before them. Right praying may easily make a man hesitant to appear before an audience. The man who is really at home in the presence of God will find himself caught in a kind of inward contradiction. He is likely to feel his responsibility so keenly that he would rather do almost anything than face an audience; and yet the pressure upon his spirit may be so great that wild horses could not drag him away from his pulpit.
No man should stand before an audience who has not first stood before God. Many hours of communion should precede one hour in the pulpit. The prayer chamber should be more familiar than the public platform. Prayer should be continuous, preaching but intermittent.
It is significant that the schools teach everything about preaching except the important part, praying. For this weakness the schools are not to be blamed, for the reason that prayer cannot be taught; it can only be done. The best any school or any book (or any article) can do is to recommend prayer and exhort to its practice. Praying itself must be the work of the individual. That it is the one religious work which gets done with the least enthusiasm cannot but be one of the tragedies of our times.
