The beliefs of Jehovah's Witnesses are based on the Bible teachings of Charles Taze Russell—founder of the Bible Student movement—and successive presidents of the Watch Tower Society, Joseph Franklin Rutherford, and Nathan Homer Knorr. Since 1976, all doctrinal decisions have been made by the Governing Body of Jehovah's Witnesses, a group of elders at the denomination's headquarters. These teachings are disseminated through The Watchtower magazine and other publications of Jehovah's Witnesses, and at conventions and congregation meetings.Jehovah's Witnesses teach that the present world order, which they believe to be under the control of Satan, will be ended by a direct intervention of Jehovah (God), who will use Jesus Christ to fully establish his heavenly government over earth, destroying existing human governments and non-Witnesses, and creating a cleansed society of true worshippers who will live forever. They see their mission as primarily evangelical, disseminating the good news, to warn as many people as possible in the remaining time before Armageddon. All members of the denomination are expected to take an active part in preaching. Witnesses refer to all their beliefs collectively as "the Truth". Source: Wikipedia (en)
