That would be those who become followers of Christ.......since the rapture.
The Bible says things get so horrible the 2nd advent of Christ is hastened or all would be killed.
That would be preaching a false gospel since Christ will leave none of His behind.
It is impossible for a pre-trib rapture since it is not found in Scripture.
It is impossible for a pre-trib rature since Scripture says that the Resurrection comes First at His Second Coming.
Brothers, we do not want you to be uninformed about those who sleep in death,
c so that you will not grieve like the rest, who are without hope. For since we believe that Jesus died and rose again, we also believe that God will bring with Jesus those who have fallen asleep in Him.
By the word of the Lord, we declare to you that we who are alive and remain until the coming of the Lord will by no means precede those who have fallen asleep.
For the Lord Himself will descend from heaven with a loud command, with the voice of an archangel,
and with the trumpet of God, and
the dead in Christ will be the first to rise.
After that, we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air. And so we will always be with the Lord.
Listen, I tell you a mystery: We will not all sleep, but we will all be changed— in an instant, in the twinkling of an eye, at the last trumpet.
For the trumpet will sound, the dead will be raised imperishable, and we will be changed. For the perishable must be clothed with the imperishable, and the mortal with immortality.
Immediately after the tribulation of those days:
‘The sun will be darkened,
and the moon will not give its light;
the stars will fall from the sky,
and the powers of the heavens will be shaken.’
At that time the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn.
They will see the Son of Man coming on the clouds of heaven, with power and great glory.
And He will send out His angels
with a loud trumpet call, and they will gather His elect from the four winds, from one end of the heavens to the other.
NOT ONE TRUMPET blast in Revelation chapters 1 thru 7.
The Trumpets begin in chapter 8
The 7th Trumpet is declared but not sounded here in chapter 10 verse 7
but in the days of the sounding of the seventh angel, when he is about to sound,
the mystery of God would be finished, as He declared to His servants the prophets.
Chapter 11:15
Then the seventh angel sounded: And there were loud voices in heaven, saying, “The kingdoms of this world have become
the kingdoms of our Lord and of His Christ, and He shall reign forever and ever!”
