It's probably so popular because it's something that could happen at anytime.
Do you have a scripture that says the rapture could happen at any time?
While I’m waiting for your scripture, here are three things that happen at His coming.
Without debating the tribulation timing, it would be good to just observe these biblical facts about the rapture, the resurrection and the destruction of the wicked, including the antichrist, which all take place
at His coming.
Point Number 1:
- The resurrection of the dead in Christ will take place at His coming, before the rapture.
For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And
the dead in Christ will rise first.
1 Thessalonians 4:16
Point Number 2:
- The rapture takes place, just a moment after the resurrection, in which all His people will be gathered together to be with Him, in the air. The resurrection/rapture is one event, at His coming.
Then we who are alive
and remain
shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord.
1 Thessalonians 4:17
Point Number 3:
The same coming of the Lord, by which the Lord gathers His people at the resurrection/rapture, also destroys the antichrist.
- Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, 2 Thessalonians 2:1
- And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. 2 Thessalonians 2:8
The coming of the Lord to gather together His people unto Himself; the resurrection/rapture is the same coming that destroys the antichrist.
Here is the full context.
Now, brethren, concerning
the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, 2 not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. 3 Let no one deceive you by any means; for
that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, 4 who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.
5 Do you not remember that when I was still with you I told you these things? 6 And now you know what is restraining, that he may be revealed in his own time. 7 For the mystery of lawlessness is already at work; only He who now restrains
will do so until He is taken out of the way. 8 And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and
destroy with the brightness of His coming. 2 Thessalonians 2:1-8
