First published in 1925, this book is a pioneer attempt to deal with conversion from the comparative as well as the psychological point of view. The work falls into two main parts. Part one is a study of the conversion experience from the New Testament and the non-Christian point of view. Part two examines conversion from the psychological standpoint.
