What’s that got to do with this Rapture thing?
The “Rapture thing” is the catching up of the church BEFORE the start of the Tribulation - which is the pouring out of God’s wrathful judgement upon the ungodly world system. The Bridegroom is removing His bride so that she/us are not suffering that wrath.
Some people think that there’s been no promise from God that believers will be spared persecution, and that is true. In fact, we should expect to undergo persecution, trials and testing because we are Christ’s. But the Tribulation is different. It is not going to be the devil’s wrath being poured out but Almighty God’s. There will be great tribulation such as has not been from the beginning of the world until now, no, and never will be again. He promises that we are not appointed unto that wrath.
