This book is dedicated to the great masses of humanity chained to the wheels of eternal physical drudgery; dragging the chariots of the godly great, and too weary in body and soul to delve into the world of books and the realms of individual thought for the knowledge so essential to give them a true understanding of the purposes of human existence. We especially seek to give vision and understanding to those who, seeing they do not perceive; and hearing they do not understand. This book is an open challenge to Christianity.
