If people actually know the pre-trib rapture didn't happen then it follows that they recognize they are in the tribulation.One of the things that clue them in is the fact that the anti-christ has been revealed,7 yr treaty etc etc.They will then know this is all true and happening before their very eyes.They can count the days till he walks into the temple,they can count the days right down to the day Jesus arrives.They literally will be able to tell people they know what is going to happen and it will happen exactly on those days.It makes no sense whatever to think that the effect this will have is to make people lose faith.The exact opposite is what one would expect.
I agree. But I think Tim LaHaye should reimburse everyone who bought his fiction series:) Just adding levity:)
