This book introduces the Bible student to the five major religions of the world: Buddhism, Christianity, Hinduism, Islam, and Judaism. In no way is it an exhaustive study. Many other books go into greater depth concerning the religions, such as those that appear in the Recommended References list and in the footnotes.
One thing that sets this book apart from others is that it is written from an Apostolic perspective and includes testimonies of converts to the Apostolic experience and doctrine.
