First, it needs to be noted that Jesus taught that one can look to various signs in nature as indicators regarding the changing of seasons, and we should also look at specific signs regarding the prophetic seasons and the coming time of redemption for ourselves and our planet.
The destruction of the World Trade Center in New York, NY is another example that many point toward as a fulfillment of events in Revelation, specifically chapters Revelation 14:8 and 18:2.
Some people have been writing in the days after the September 11th event about the question of whether the event fulfills Revelation 18’s pronouncement of judgment on Mystery Babylon. Others deny that the Mystery Babylon of Revelation 18 is even speaking about America (and some inexplicably deny that the USA, the greatest nation in history, is even mentioned in prophecy). While it is true that Revelation 18 is not referring merely to the destruction of the World Trade Center, it is clear to me that the final destruction of the United States of America is mainly what Revelation 18 is about—at least economically.
