Matthew 24:21 – “For then shall be great tribulation,…”
The Rapture has taken place and we that are saved are in Heaven. Those that are not saved are on Earth enduring this Tribulation Period. The Tribulation covers Revelation 6-19. It is also discussed in numerous passages such as: Daniel 9-12; Matthew 24; Zechariah 12-14, and many others. The Tribulation Period is divided into two separate 3 ½ year segments. In the first 3 ½ years the Antichrist will try to unite everyone in peace. He then will offer the abomination of desolations (Dan. 9:27; 12:11; Matt. 24:15) upon the altar in the Temple and the last 3 ½ years will be Hell on Earth. In Revelation 5 Jesus opens the seals of the Seven-sealed book and He is the one that pronounces these judgments during the Tribulation.
