...The rapture is when Christ will come down to the clouds...
I believe that we will be caught up to meet Jesus coming "in the clouds" on his way down to set his feet on the earth.
"The Son of man coming in the clouds...
with a great sound of a trumpet,
and they shall gather together his elect"
(Matthew 24:30-31).
"We which are alive and remain unto the coming of the Lord...
with the trump of God...
shall be caught up together with them in the clouds, to meet the Lord"
(1 Thessalonians 4:15-17).
I don't believe that the scriptures teach two different comings "in the clouds,"
or two different "last" trumps (1 Corinthians 15:52),
or two different raptures.
Because 1 Thessalonians 4:14-17 shows Jesus "coming," but doesn't show him landing on the earth, some believe it refers to a part-way coming of Jesus whereby he comes down only as far as the clouds and then returns to heaven. But note that Matthew 24:29-31 and Revelation 19 don't show Jesus landing on the earth either. Do some then believe that Matthew 24:29-31 and Revelation 19 are also not the 2nd coming?
Note that 1 Thessalonians 4:14-17 doesn't show Jesus returning to heaven. Acts 1:11 says Jesus will "come" just as he left: he won't come only as far as the clouds and then return to heaven again, just as he didn't leave only as far as the clouds and then return to earth again. He went from the Mount of Olives to the clouds to heaven, he will come from heaven to the clouds to the Mount of Olives (Zechariah 14:4). There's no 3rd coming of Jesus.
...The sheep will remain in their mortal bodies...
I believe the sheep and goat judgment of all nations (Matthew 25:32-46) is not until the white throne judgment after the millennium (Revelation 20:11-15), when I believe the sheep will enter the eternal kingdom prepared beforehand (Revelation 21:2-3), and the goats will enter everlasting punishment (Revelation 20:15). Note that only the Antichrist and False Prophet go into everlasting punishment at the 2nd coming (Revelation 19:20).
Note that the sheep "inherit the kingdom" (Matthew 25:34), so they must be in resurrected bodies, for "flesh and blood cannot inherit the kingdom" (1 Corinthians 15:50).
Note that the sheep and goats are judged by what they did (Matthew 25:40, 45), just as those at the white throne judgment are judged "according to their works" (Revelation 20:12).
I believe we should all pray that we might be counted worthy to escape the coming tribulation:
"Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man" (Luke 21:36).
But note that Jesus is speaking to the same believers, the same "ye," in Luke 21:8-35 that he is speaking to in Luke 21:36.
I believe we will escape the entire tribulation and stand before the Son of Man (Luke 21:36) only if we die before the tribulation starts (Isaiah 57:1, 2 Corinthians 5:8, Philippians 1:21-23).
Note that Revelation 3:10 doesn't promise us a pre-trib rapture, but simply promised the 1st century church of Philadelphia that it would be kept from the hour of trial, which was probably a great persecution in their own time, and they weren't raptured.
Note that no scripture promises us a rapture before the tribulation. Jesus says he will come to gather us together "immediately after the tribulation" (Matthew 24:29-31), and Paul says Jesus' coming to gather us together must "destroy" the Antichrist (2 Thessalonians 2:1-8).
Note that we Christians are referred to throughout Revelation (6:11, 7:14, 9:4, 12:17, 13:7-10, 14:12-13, 15:2, 16:15, 18:4, 20:4), and there are no Christians outside of the church (Ephesians 4:4-5).
