I saw a couple of movies based on these books. I'm impressed by Mr. LaHaye's research into Biblical End Times.
Please note, there are other serious studies about these times in other religions.
As you can see from the picture on the left, the depiction of Christ's return is on a horse. In other pictures of this event, angels with wings fly down with him to The Mount Of Olives.
As I've stated in other entries in this blog, the visions of Christ, God, angels and miraculous events usually come from medieval artists. This is part of the Christian dogma box. It's canned Christianity which doesn't need a personal viewpoint or inner vision.
Any advanced alien civilization which has intentions of conquering Earth would find allies in Christian Fundamentalists if they (the aliens) could counterfeit the events in Left Behind with high tech illusions.
Believers singing the same tune and marching to the same drummer are examples of group think created by biblical experts.
Another kind of group think caused the stock market to lose 40% of its value because economic experts led investor-sheep over the cliff.
