In reply to your 9/11 post at A Post-Trib Rapture scenario (fivedoves.com) saved born again believers won't be here on Earth during the wrath to come during the great tribulation period.  Please see the following verses:

1Thess. 1:10, "And to wait for his Son from heaven, whom he raised from the dead, even Jesus, which delivered us from the wrath to come.

Rev. 11:18, "And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth."
