ALL Christians will be taken in the Rapture. You can't lose your salvation either. We're sealed with the Holy Spirit at the moment of salvation.

The events in Revelation won't be coming right after the Rapture. They will happen years later.

Denominations won't disappear after the Rapture. People will still disagree about the role of the Holy Spirit, the role of women in the church, and how much of the Bible to take literally.

The Rapture won't necessarily cause those who have been left behind to come to Christ. Satan will have a lie to explain the Rapture. Mankind made a sudden evolutionary leap forward. Christians have been left behind because they're not as highly evolved as the rest of us. Once they give up their false religion they will rejoin us.

I think few people will repent and accept Christ after the Rapture. Too many people will love their sexual sin too much to give it up. That includes people who grew up in a good church and were raised by Christian parents. They're just as likely to serially cohabit as those with no exposure to Christianity.

Millions, if not billions, will refuse to repent.

(Revelation 9:20-21 NIV) The rest of mankind that were not killed by these plagues still did not repent of the work of their hands; they did not stop worshiping demons, and idols of gold, silver, bronze, stone and wood--idols that cannot see or hear or walk. {21} Nor did they repent of their murders, their magic arts, their sexual immorality or their thefts.
