What are these signs that have recently become viable for the first time in history? Jesus gave a number of them. For example, in speaking of events that would precede His second coming, He warned of a time of unprecedented destruction that would be so severe that “except those days should be shortened, there should no flesh be saved...” (Matthew:24:22). Such a statement was a puzzle to past generations: How could the destruction of all life on earth be threatened through bows and arrows, swords and spears, or even the conventional weapons of World War II? Our generation, however, has developed and stockpiled arms inconceivable in the past, which actually have the potential to destroy all life on this planet. So we are the first generation in history for whom this particular prophecy no longer awaits some future development to make it possible. The prophesied destruction (which Christ will intervene to stop) could occur at any moment.
