With its easy-to-follow, question-and-answer format, this book allows readers to quickly discover: who founded Jehovah's Witnesses and why; why medical care essential to life is refused; why few Jehovah's Witnesses look forward to eternal life in God's presence; how many Jehovah's Witnesses prophecies have failed--and why; and how Jehovah's Witnesses view and interpret God's Word. Whether looking for specific teachings or an overall understanding of Jehovah's Witnesses' beliefs and practices, readers will find that this book delivers the information in a concise, practical manner.
