Mateus 24

21 Because then there will be a great tribulation, such as has never been since the beginning of the world until now, and never again will be.*There has always been tribulation and distress in the world, and continues to be, but nothing to compare with the Great Tribulation, which has not yet happened. 22 And unless those days were cut short no flesh would be saved;*Adding up the percentages of destruction in Revelation, it appears that only one sixth of those who are alive at the beginning of the Great Tribulation will still be alive at its end. If six billion go in, only one billion will come out. So much for the overpopulation problem! but for the sake of the elect those days will be cut short.*Just who are the "elect" here (and in verse 31), if the Rapture has already taken place? I believe there will be many millions of conversions immediately after the Rapture—unsaved church members who are left behind. And if the Rapture is partial (Matthew 25:1-13), all the lukewarm Christians will all of a sudden get serious.
