Does anyone know of a movie or series about the Tribulation that I saw in the late 1980's or early 1990's?

I saw a movie in 1989-1990 about the tribulation and want to know the name. It was not Left Behind with Kirk Cameron! The premise was that the Christians had already been taken to heaven and the remaining Christians that were left behind here sent to a camp. The pastor of the church had been left behind and the main character as I remember it was a girl who was in her early teens. The end of the movie I think they were all about to be shot in a firing squad.
