The Trumpet has a lengthy history of properly forecasting important world events and trends utilizing Bible prophecy. This tradition may be traced back to the late Herbert W. Armstrong's Plain Truth magazine, which was founded in 1934. The first issue of Modern Prophecy was published in 1943 by Harry Rimmer, who had been preaching about Bible prophecy for many years through his radio program. Modern Prophecy quickly became a worldwide phenomenon, with readers from every country in the world subscribing to its monthly journal. The magazine covered topics such as politics, economics, science, religion, and culture, and always emphasized that Bible prophecy controls world events and that people should look up Bible verses related to these topics. In addition, it listed current news stories and individuals/organizations that it believed were involved in espionage or other dark practices. In 1966, after the death of its founder Harry Rimmer, responsibility for publishing Modern Prophecy was taken over by the Worldwide Church of God (WCG). Although Harry Rimmer had been teaching Bible prophecy for only ten years when he died, the church decided to continue publishing his work because it believed this was one of the ways Jesus Christ had told him to spread the word about end times.
