"To my readers I would say that, although the main subject of the tripartite nature of man is such a controversial one, this book is not entered as a part of the controversy. Such a course would only be to contradict its main contention—that Divine things can only be entered into by revelation and never by reason. Indeed, I have no wish that anyone should read this book unless they are really exercised about reality and spiritual things. I would ask for openness of heart as the one concession to the Spirit of truth if, peradventure, He might be ready to use what is written here for enlightenment.
"The book goes out with a prayer which comes from long ago, 'that the God of our Lord Jesus Christ, the Father of glory, may give unto you a spirit of wisdom and revelation in the knowledge of him; having the eyes of your heart enlightened' (Eph. 1:17)."
