Dear Caspar & Fellow Watchers,

I think you may be confusing the Rapture of the Body of Christ with the 2nd Coming of Christ. Refer to: 2 Thessalonians 2:1-4

1 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.

Verse 1 refers to the Rapture as "our gathering together to Him".

Verse 2 refers to the beginning of the Tribulation as "the day of Christ".  

Verse 3 & 4 refer to the Antichrist as "the man of sin".

Therefore, the Tribulation can't begin till the man of sin is revealed. And the man of sin can't be revealed till the Rapture takes place.

1) Rapture
2) Man of Sin
3) Tribulation

All the Best
Mike P
