If you wish to play word games, take them somewhere else. Rapture comes from the Latin word raptura, from Latin raptus, which is a translation of the Greek verb "harpazō" from which we get "caught up."
1 Thes. 4
17 Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air.
Do you see those two words, "caught up?" That is what we call today the rapture of the bride. No worries, since you don't believe in it, God will make absolutely sure you are not one that will be caught up. YOu will be left behind to see the Beast of Rev. 13.
Rev. 20 & 21 search on "coming" results:
Revelation 20:1
Then I saw an angel coming down from heaven, having the key to the bottomless pit and a great chain in his hand.
Revelation 21:2
Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband.
There you have it. An angel coming....and the New Jerusalem coming. Seems you missed it yet again. There IS NO coming of our Lord in Rev. 20 or 21. Let me help you, for it is very clear you need help:
Rev 19
11 Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war. 12 His eyes were like a flame of fire, and on His head were many crowns. He had a name written that no one knew except Himself. 13 He was clothed with a robe dipped in blood, and His name is called The Word of God. 14 And the armies in heaven, clothed in fine linen, white and clean, followed Him on white horses.
This is His coming. Destination? Israel, Middle East, planet earth. He comes about 7 year previous to this, to get His bride, now here He is coming WITH His bride, and the angels. For the posttribbers, there is no rapture here at His coming on the white horse. It came 7 years previous.
Bottom line? Pretribbers can read simple English. Paul described VERY CLEARLY a catching away of the Bride of Christ. We call it the rapture of the bride. Anyone can be ready and be snatched up to meet Him in the air. On the other hand, anyone can refuse, and be left behind. Anyone can follow Luke 21:36 and PRAY to be found worthy to excape what is coming. But sadly, many are confused, and cannot believe in the catching away of the bride. They will be left behind. Then, they will be beheaded. They will be OVERCOME by the Beast.

Lamad, since belief in the rapture, being a pre-tribber, a post-tribber or whatever does not effect our salvation. Be honest - We really don't KNOW! We hope we understand the scriptures. We try to put together the Word of Jesus, the OT scriptures of Isaiah, Daniel, Ezekial, Joel, Paul's writing and Revelation. We are not sure. We all have different opinions and really think we have it down pat. It really doesn't matter that much. We are told by Jesus to be ready! That's where our emphasis should be. God will take care of us. Remember, He loves us as a parent for a child. Jesus told us how to be ready. WE MUST BE READY!!!
