Again, in one of the prominent smaller cities of America, a club of sceptics, leading business and professional men, had held weekly meetings for many years. They challenged any one to meet one of their widely known lecturers in a public debate on Christianity and Infidelity. A preacher accepted the challenge. During the debate some of the sceptics became Christians. The president of the debate, a sceptic, is now an earnest follower of the Lord Jesus, having been convinced and having accepted Him as Saviour. The debate was held years ago. So convincing, so overwhelming, was the evidence produced by the defender of Christianity, that the club of sceptics has never held a meeting since the debate. Similar facts could be produced indefinitely, but these three are sufficient to show the most discouraged, the most hopeless sceptical reader, that there is at least a possibility of his yet finding the truth. Is not a bare possibility, where there are so tremendously important eternal issues at stake, sufficient to cause him to at once begin a thorough, prayerful, honest investigation? A reflection before closing the Introduction: one hundred years from now, and you, reader, will not be among the living. Where will you be? God has given you a will and the power of choice. Will you will, will you choose, to make an honest, persistent investigation? Tremendous consequences turn on your decision,--your own future destiny, the destinies of others over whom you have an influence. Do not dally with delay. Begin now an honest, earnest, painstaking, prayerful investigation. Get and read the two books suggested, and then finish reading this book. If this course does not settle your difficulties, read on, study on, pray on, and God's promise is sure, that you shall find, that you "shall know"! _FOR FURTHER STUDY_: A brief list is here given of books that will be helpful to sceptical readers: "Why Is Christianity True?" by E. Y. Mullins. (One of the most learned Presbyterian theological professors in America, asked to give the names of six of the best books to convince sceptics, replied, "I shall not do it; I shall give one,--'Why Is Christianity True?' by President Mullins of the Southern Baptist Theological Seminary; that is sufficient"); "The Fact of Christ," by Simpson; "The Meaning and Message of the Cross," by H. C. Mabie; "The Resurrection of Our Lord," by W. Milligan; "Many Infallible Proofs," by A. T. Pierson; "The Cause and Cure of Infidelity," by Nelson; "The Word and Works of God," by Bailey; "The Character of Jesus," by Bushnell; "Hours with a Sceptic," by Faunce; "The Miracles of Unbelief," by Ballard; "Creation," by Arnold Guyot; "The Collapse of Evolution," by Townsend; "The Problem of the Old Testament," by James Orr; "Did Jesus Rise?" by J.
