Signs of the End Times - Dr. David Reagan http://www.lamblion.com/articles/articles_signs3.php
The re-establishment of the nation of Israel is a classic example of an end time historical sign. Over and over again the Hebrew Scriptures prophesy that in the end times, right before the return of the Messiah, the nation of Israel will be re-established (Isaiah 11:10-12; Ezekiel 37:1-12; Amos 9:13-15; and Zechariah 12:1-3). Jesus emphasized this sign in Matthew 24 when He told us to watch for the rebudding of the fig tree (a symbol of Israel). When that happens, He said, the generation that sees it "will not pass away until all these things [the return of the Lord] take place" (Matthew 24:34).
The book of Revelation is full of technological signs concerning the end times. Take, for example, the prophecy that one-half the population of the world will die in the first three and a half years of the Tribulation (1/4 in the Seal Judgments and 1/3 of those remaining in the Trumpet Judgments — Revelation 6-9). How could such unparalleled carnage occur apart from the development of nuclear weapons and their missile delivery systems?
Or consider the prophecy that when the two great witnesses of God are killed by the Antichrist in the middle of the Tribulation, the whole world "will look upon their dead bodies for three and a half days" (Revelation 11:9). How could this be possible before the development of television and satellite transmission?
Another prophecy in Revelation that has been waiting for historical developments is the one that states there will be an army of 200 million soldiers that will march across Asia toward Israel during the period of the Tribulation. At the time that prophecy was written (95 AD), there were only 200 million people on planet earth! It took 1,600 years for the population of the earth to double to 400 million. In fact, the earth’s population did not reach one billion until 1850. This century has experienced a population explosion due to the advent of modern medicine (keep in mind that the first antibiotic, penicillin, was not discovered until 1928!). Today, the earth’s population has just passed the six billion mark, and one Asian nation alone — namely, China — could easily send an army of 200 million, as prophesied in Revelation.
