The Rapture is told of in scripture as being a reward to the faithful. How is it a reward to have to go through God's lifting of His Holy Spirit from the earth, and the putrid vlieness that will ensue as Satan 's minions are left to do as they will here with no restraint?
Also, the Rapture is followed by the wedding feast, a great and joyous celebration lasting days in Heaven as Christ is wed to His bride, the church. This is all part of the reward; a great blessing of grace received by the faithful for having had faith even before having witnessed the evidence of scripture's inerrant accuracy as displayed by the Rapture itself... hundreds of millions of people simply disappearing from the planet in an isntant.
It makes no sense for the Rapture to be foretold as an event which saves the church from the trials to come, and still have the church left here on earth as the Antichrist and Satan's demons take over.
If one believes in the unblinking, infallible Truth of God's Holy Word in the bible (there are many "Christians" who do not so believe), and more specifically, if one believes in Jesus' promises to the faithful as told in Revelation, then logic insists that the Rapture happens pre-Trib.
Though the millions saved out of the Tribulation will be difficult to count, so great will be their number, it will be far harder to be saved by faith after the beginning of the Tribulation. The bible is very clear on this. It fails to pass the smell test to believe that those who accepted Christ as Lord and Savior prior to the Tribulation would be left to suffer that, especially given that Jesus himself distinguishes (again in Revelation) between those who had faith before the Trib, and those "saved out of the Tribulation."
