Kindly read and study Revelation 19. The Marriage of the Lamb takes place immediately before the second coming, which means that the saints (the Church, the Bride of Christ) have already been raptured in order to become the Lamb's Wife. Therefore it is impossible for the rapture and the second coming to coincide.
I agree.
I now recall having a discussion with someone recently on this same line (Keraz, I think), and he was saying the wedding supper takes place on earth after Armageddon. I was asking what sort of a setting would that be for a wedding, i.e. with dead corpses covering the planet? He tried covering by saying the scriptures never specify how long it will be before the wedding actually takes place after His return, but I think he was fudging things. The context suggests the wedding is the primary reason why He returns to begin with (Revelation 19:7-10). The secondary is then to destroy the nations and the cast the beast and the false prophet into the Lake of Fire (Revelation 19:11-21).
Granted, there is a break in between these two passages that Brakelite will likely say does not exist. But it still begs the question: What sort of a wedding is kicked off by with the worst bloodbath in history?
