I have in mind a fine, thoughtful fellow, graduate of a famous college and a church-member, whose very thoughtfulness, and the knowledge of his religious activity in former years, led me, when he entered my class, to take for granted his Christianity. After weeks of teaching, it was only a chance question, in private conversation, that led him to the frank admission that skeptical college friends had absolutely destroyed his faith in Christ and the Bible, leaving him with only a sad and bewildered hold on the God of nature. What Sunday-school teacher has not been startled thus with disclosures of his own carelessness in taking things for granted? It is a mistake constantly to advertise skepticism by warning our scholars against it, but it is no mistake to arm them against it. No teacher has mastered his lesson until he has mastered every doubt regarding it that any of his scholars is likely to entertain. "Will this punishment seem unjust? this event fabulous? this person mythical? this doctrine unreasonable? this miracle unreal? this author apocryphal? these men and women mere creatures of imagination?" Such questions as these are important for the teacher to consider,--_to consider_, not ask in the class. Because to the teacher the account is more true and vivid than an extract from yesterday's newspaper, he takes it for granted that his scholars so regard it. They may put the lesson story in the same category as Baron Munchausen or "The Ancient Mariner," and such a teacher would be none the wiser. I know of nothing _in the way of study_ that is so capable of firing a Sunday-school teacher and class as Christian evidences. Remember that this also is a study of the Bible. Why is it ordinarily thought so dull? It is full of snap and point. Professor Fisher's short "Manual of Christian Evidences," published by Charles Scribner's Sons at seventy-five cents, stands next to my Bible as an aid and inspiration in teaching that Bible. I keep several copies, and all of them are usually in the hands of earnest scholars. Often when they are returned the compliment is, "That book helped me so much that I have bought a copy of my own." That means the conversion of a doubting Thomas. "Why!" exclaimed one such reader, "I never knew before that there was anything to prove Christianity but the Bible, or anything but the Bible to prove the Bible."
