Brothers, that wasn't my question.
The characters heard the gospel but didn't believe. The Bible says that the ones who hear but don't believe when Rapture happens, can't be saved during the tribulation. Is left behind wrong?
I cannot attest to the accuracy of the Left Behind series either as I have not seen the movie nor the books. However the Bible tells us that all will have heard the Gospel by the time the tribulation starts yet it also tells us that many will be tribulation saints. Tribulation Saints are those that turn to the Lord during the tribulation.
Mat 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
