If Billy Sunday had not been an athlete he would not today be the physical marvel in the pulpit that he is; if he had not been reared in the ranks of the plain people he would not have possessed the vocabulary and insight into life which are essential parts of his equipment; if he had not served a long apprenticeship to toil he would not display his present pitiless industry; if he had not been a cog in the machinery of organized baseball, with wide travel and much experience of men, he would not be able to perfect the amazing organization of Sunday evangelistic campaigns; if he had not been a member and elder of a Presbyterian church he could not have resisted the religious vagaries which lead so many evangelists and immature Christian workers astray; if he had not been trained in three years of Y. M. C. A. service he would not today be the flaming and insistent protagonist of personal work that he now is; if he had not been converted definitely and consciously and quickly in a rescue mission he could not now preach his gospel of immediate conversion. All of which is but another way of saying that Sunday was trained in God's school. God prepared the man for the work he was preparing for him. Only by such uncommon training could this unique messenger of the gospel be produced. A college course doubtless would have submerged Sunday into the level of the commonplace. A theological seminary would have denatured him. Evidently Sunday has learned the lesson of the value of individuality; he prizes it, preaches about it, and practices it. He probably does not know what "_sui generis_" means, but he is it. Over and over again he urges that instead of railing at what we have not enjoyed, we should magnify what we already possess. The shepherd's rod of Moses, rightly wielded, may be mightier than a king's scepter. As we approach the development of the unique work of Billy Sunday, which is without a parallel in the history of evangelism, we must reckon with those forces which developed his personality and trace the steps which led him into his present imperial activity. For he has gone forward a step at a time. He followed the wise rule of the rescue mission, that the saved should say so. At the very beginning he began to bear testimony to his new faith. Wherever opportunity offered he spoke a good word for Jesus Christ. In many towns and cities his testimony was heard in those early days; and there was not a follower of the baseball game who did not know that Billy Sunday was a Christian.
