This book has been written for two reasons: first, because it seemed to be needed; second, to save the writer time and labor. Letters are constantly coming in from all quarters asking how to study the Bible. It is impossible to refuse to answer a question so important as that, but it takes much time to answer it at all as it should be answered. This book is written as an answer to those who have asked the question, and to those who may wish to ask it. Nothing is more important for our own mental, moral and spiritual development, or for our increase in usefulness, than Bible study. But not all Bible study is equally profitable. Some Bible study is absolutely profitless. "How to study the Bible so as to get the largest profit from it," is a question of immeasurable importance. The answer to the question, found in this book, has been for the most part given in addresses by the author, at the Chicago Bible Institute, before the summer gatherings of college students, at ministerial conferences and Y. M. C. A. conventions. Many, especially ministers, who have heard these addresses have asked that they might be put in a permanent shape. I have promised for two years to comply with this request, but have never found time to do so until now.
