What does the bible say about some believers remaining here on earth?

lol... huh? when Christ comes to collect His church, to snatch His pearl of great cost, there wont be any believer remaining on the earth. there will be a whole new season wherein people will take the evidence of the scripture and proof of the rapture and become the remnant God has always appointed. they will seek to help other people and this will be countered by the government, they'll ban the Bible and outlaw Jesus and kill Christians who don't confess caesar as lord. but when He comes to extract His beloved ones, not a single one of them will remain here. the rapture is a homecoming and reunion and it wouldn't be so if the whole family were not present.
