Thanks.
Giovanna,
I hope you won’t take this wrong, but it is not we post-tribbers who have the burden of proof to prove this thing you ask. It is the pretribbers.
Christ himself in the Olivet Discourse (Matt. 24) laid the basics down. He taught us not to look for his coming except the one described in v. 29-31 “immediately after the tribulation of those days.”
As to the epistles, they merely followed Christ’s teaching already established in Matt. 24. They said nothing about another coming other than the one in Matt. 24:29-31 after the tribulation - in which the trumpet sounds and the saints are gathered.
And there is no reason that the Revelation would insert something that had not been already previously established. Therefore the post-trib second coming and rapture in Revelation is the same one in Matt. 24 and in the epistles.
It is the pretribbers who have the burden of proof to prove otherwise - that Paul introduced another coming and rapture additional to the one Christ taught.
The passages in Thessalonians and elsewhere that pretribbers use are merely talking about different aspects of the same event Jesus described in Matt. 24:29-31. If it were a new additional coming, then Paul would have said so. Hence, it is the same one.
