Many supposed signs or dates of the end have been proposed and they have all so far proven unreliable. Otherwise, the end should have already come upon us many times over. Nevertheless, there are reliable signs given in the Bible, even if most readers and teachers overlook or misunderstand them. One major sign of the end that Jesus spoke about will be unmissable, although to discuss it can be depressing. But if you dare, learn what the Book of Revelation says about this event that Jesus hinted at, a reliable end time sign that has to do with the most powerful nation on earth in the end times.
