Rapture or Second Coming?
The verses you quote distinctly do say that after the tribulation of the time that the LORD SHALL indeed appear. And I have no doubt that he will. But it is a decription of the LORDS return with his already raptured (caught up church). TRANSLATION: VS 31. And he shall send his angles with a great sound of a trumpet and they shall gather togeather his elect from the four winds; from one end of HEAVEN not earth. to the other. THE GREEK WORD PRONOUNCED OO-RANOS HEAVEN GODS REALM AIR. This is the CHRIST returning for final battle with his caught up church.
This passage is the next closest passage to the only rapture passge in the Bible. It even has more in common than the popular 1 Cor. 15:50-54. Also, the word "rapture" is not found in any of these passages nor anywhere else in scripture. All three of these label this event the "coming." I fully understand the pre-trib framework but find no evidence for it biblically. The Bible nowhere speaks of two comings, nowhere says "before the Tribulation," nowhere uses the word "rapture" and nowhere says that we are exempt from tribulation. Instead, our Lord says that "in the world you will have tribulation" (John 16:33). As much as I would like to (and I really would), I can find no evidence for a pre-tribulation rapture.
