Our Catholic friends seem to think that the Rapture is not a Biblical teaching.
There's no doubt that the Bible teaches a "catching up" (rapture) of the Believers. The big debate is when. Sadly this non-salvation issue has divided the Body ever since it came into existence in the 19th century.
I wondered about the popularly taught theories for decades until, I believe, the Lord revealed to me what is going to happen (not WHEN but WHAT).
When the Lord returns He will establish His Millennial Kingdom here on this Earth. For that thousand years those who have rejected God's plan of salvation and Satan and his demons will be removed from this Earth (Psalm 37: 9-11, 20, 22, 29, Matt. 24: 40-41). I understand the Lord to say those represented in those verses are NOT the Believers.
At the end of the thousand year Kingdom the Believers will be removed and God will cast Satan, his demons and those who rejected His plan of salvation back down to Earth for the "Great Tribulation". After that God will destroy this Earth and the Heavens and create a New Earth, Heavens and the New Jerusalem (See Rev. 21). Our eternal home will be the New Earth (NOT Heaven as has been taught by many because Heaven is GOD'S domain, "headquarters" so to speak, where all the records and rewards are kept). We have been taught that we will go to Heaven based on the Scripture where Jesus said He was going to sit at the right hand of God and that we would be with Him. That is based on the erroneous assumption that Jesus never leaves Heaven and that is where He is preparing a place for us.
I know this view of the end-times will rattle some cages and perhaps even upset some because they have bought into one of the popular "Rapture" theories. But you need to remember two things: 1. This is not a salvation issue and 2: I'm just the messenger.
