I was born again in 1981 and I came to Christ after seeing the movie "Thief in the Night" at an Assembly of God church my girlfriend at the time talked me into attending. As most know, that film is based upon the pre-trib rapture view. That church held to that view and every Sunday night service was focused upon end-times matters. So most of my early born again learning on the matter was from books and sermons from the 1970s and early 80s. Everything I heard at the time indicated the Anti-Christ would not be known until after the Rapture. Over the past couple of years I'm hearing more and more that Christians will be here when the Anti-Christ takes the world stage and we will know who he is; the Rapture taking place sometime after that.
Why the shift from the predominate view being Christians wouldn't know who the Anti-Christ was because we would be raptured prior to his revealing, to the current view which says the Anti-Christ will be revealed before the Rapture so Christians will know who he is?
