Scripturally the rapture has been predicted to happen or take place I know this question is coming as a doubt because of the possibility of whether the rapture maybe true or not, but just like the bible predicted the birth of Jesus, God gave John the beloved a revelation in the island of patmos and he saw the processes of how the rapture was going to take place and that was what he recorded in the book of revelations. There are so many bible verses that spoke about the coming of the rapture and here are a few of them
PHILIPPIAN 3: 20 & 21 But our citizenship is in heaven. And we eagerly await a Savior from there, the Lord Jesus Christ, 21 who, by the power that enables him to bring everything under his control, will transform our lowly bodies so that they will be like his glorious body.
II CORINTHIANS 5 vs 10; For we must all appear before the judgment seat of Christ, so that each of us may receive what is due us for the things done while in the body, whether good or bad.
The rapture can be known as the taking away of people into heaven when the seventh trumpet has been blown just like it was written in the book of revelation, it says that those who are saints and have been washed in the blood of the lamb, whether dead or alive will be caught up in the sky when jesus appears.
The bible is never wrong even when you look at the bible its predicted the end of days where nations will rise against nations and if you look currently at the world now there are so many things like war, crime and terrorism which was actually predicted in the bible beforehand. The rapture will definitely take place but nobody knows the time just like jesus said he said he will come like a thief in the night and he also said that not even the angels in the heaven knows when the rapture will take place so the rapture will definitely take place because the signs and predictions of the end of days are already happening
