[Cronos]

exactly. The reason Paul doesn't mention this 19th century rapture idea as occuring before the appearance of the antichrist and before the second coming is simple: it never entered into his mind that anyone would believe Christ would rapture His Church before the final Eschaton

In the apocalypse, that is referred to as the battle with Gog and Magog, Christians will participate in that confrontation because there will be no secret rapture before it. Our comfort rests in Him who will emerge from that confrontation as the Victor.

THAT is the reassurance Paul offers, not the promise of an escape from the great Tribulation.

It would help you, perhaps, to look up the Pseudo-Ephraim, written as a sermon between 400 and 600 which addresses the Pre-Tribulation Rapture of The Body of Christ. Perhaps that FACT would stop this obsession you have over Darby. Perhaps ... but not likely since yours is an obsession sourced in a demonic agenda.
