This is my understanding of what I have written below as I study the scriptures. Not everyone is going to agree, but let's have a civil discussion on this only giving what you believe without disrespecting the views of others as we well know these types of discussions can become heated. Let's respect the Terms of Service as we discuss this. Thank you.
The word Rapture is not found in scripture as scripture calls it being caught up at the last trump, meaning the seventh trumpet of God, 1 Corinthians 15:51-58; 1Thessalonians 4:13-18, is explained in these verses if you read them for what they say. Rev 14:6-20 is the precursor for the catching up of the saints that makes up the true body of Christ. This is separating the wheat from the tares or in other words saints from sinners as sinners being those who have taken the mark of the beast in Rev 13. Christ is sending the angels to separate the wheat from the tares to protect His own in safety from the seven vial judgments that will take place, Rev 15:1-8; 16:1-21.
After mystery Babylon is revealed and then destroyed, Rev Chapters 17, 18, heaven rejoices her destruction as the beast and false prophet are cast into the lake of fire. It is not until we read in Rev 19 of Christ second coming as we, His Bride, have prepared ourselves, those in the grave and we that are still alive, to be caught up together to the clouds and given our new glorified bodies as we are arrayed in fine linen, clean and white then meet Christ in the air, Matthew 24:29-31; 1Thessalonians 4:13-18. We are then joined to our Groom (Jesus) for the marriage supper (union) of the Lamb and His Bride. Fine linen means we are now arrayed in Gods righteousness.
