This book aims to trace the main milestones in the history of Jehovah's Witnesses along the line of its correspondence to the words spoken by God Himself: “If a prophet speaks in the name of the Lord, but the word does not come to pass and is not fulfilled, then the Lord did not speak this word, but spoke this a prophet in his boldness, “do not be afraid of him” (Deut. 18:22). In other words, we will try to determine by this sign whether we should “fear” and, therefore, obey Jehovah’s Witnesses and whether their word is the word of God. In this work, I deliberately refused to analyze the beliefs of Jehovah’s Witnesses, since they will be discussed in detail in the book "Refutation of the Teachings of Jehovah's Witnesses", which is currently being written.
