Dr. Walter Martin, renowned author of the classic bestseller The Kingdom of the Cults, now offers a concise and accessible guide to the Watch Tower Bible and Tract Society, better known as Jehovah's Witnesses. With a rich history spanning over a century and a global following of over one million, this organization poses a significant challenge to biblical Christianity wherever the authentic Gospel of Jesus Christ is proclaimed. In this booklet, Martin expertly uncovers the roots of Jehovah's Witnesses, tracing their lineage back to the fourth-century Arians, who viewed Jesus Christ as merely a created being. He then delves into the core teachings of the J.W.s, meticulously comparing them with Scripture. For a more in-depth exploration of this topic, readers may refer to Martin's comprehensive work, Jehovah of the Watch Tower. Other notable booklets by Dr. Martin include Christian Science, Herbert W. Armstrong, Mormonism, and The New Spirituality.
