ACCORDING TO TALMUDIC TRADITION, WE ALREADY HAVE THE SIGN OF THE DESTRUCTION OF THE WORLD

Whoa, this is really interesting stuff:

The Orion Comet Sign

The Talmud records the oral tradition of the Jews (Berachoth 58b) which tells us that when a comet passes through the constellation Orion, the world would be destroyed. The Comet Hale-Bopp would appear to be a fulfillment of this sign. It entered the region of the sky known as Orion on May 20, 1997 and exited on June 16, 1997. Another comet appeared shortly afterward whose path paralleled that of Hale-Bopp. This comet, 1998 J1, or, "SOHO," has passed through Orion as well, and according to Bob Wadsworth's study of these two celestial objects, both entered the ancient constellation Argo on the same day, June 14, 1998. SOHO entered from the northwest, and Hale-Bopp, from the southwest.

The Noahic Flood Comet Sign

According to recent orbital calculations by astronomers, (re. Daniel W.E. Green of the Harvard-Smithsonian Center for Astrophysics) this same comet we now call Hale-Bopp passed through the inner solar system once before - about 4210 years ago. The Flood began 1656 years from Adam, in the Fall of the year we know as 2238 BC. That was 4234 years ago. If the comet appeared somewhere around 4210 years, it was the time of the great flood. According to what is recorded in the Seder Olam Rabah, an ancient Jewish text, we may observe that a comet appeared at about the time Noah began building the ark. It was probably the comet we know now as Hale-Bopp! Do you think that this comet may have been a sign of the impending destruction of the world by water? I do!
According to our Lord's words in Matthew 24:

As it was in the days of Noah, so it will be at the coming of the Son of Man.

Matthew 24:37

By the sign of the rainbow, God's promise not to destroy the earth again by water still stands. However, the Earth will be destroyed by fire. What was evidently a portent of the first destruction could well be the same for the next.
