I don't think the movie used Christianity as a plot gimmick. This was a remarkable movie about living by faith instead of sight as well as the way that God always preserves his Word regardless of how much man screws up the world. As for the violence and brutality, at times it did feel a little over the top, but there was not much you would not find in the Bible itself. The movie is clearly rated R for violence and language. You can choose not to see it.
moreover....the premise is that the world has basically been incinerated, and (as Eli says) many people say that whatever happened was caused by the Book. There is a real post-armageddon feel to this. The viewer is not sure just what happened, except that the Bible was at the center of it all - which, by the way, is very good theology.
Now...accept the preceding carnage at face value, and then you have to wonder: would the survivors be illiterate? yes. would they use naughty words? yes, i think they would. would they be violent? you betcha.
if they had NOT had the naughty words and the violence, then they could not have offered the opening premise.
so I think this movie just states the truth of the depravity of man.
But the larger and much more interesting Truth comes out, loud and clear: A sovereign God will preserve his Word, supernaturally.
That is an awesome (and true) message.
I would suggest walking through some of the most Godless gangland’s in the SI and other hell holes in the world. They are full of people acting like animals. I thought it was a little over the top, but not too far.
Like I said, there's a way to tell this story and this wasn't it.
If you look at what the world would look like if there were no Christians, save Eli and his Bible, I don't think the movie would be that far from the mark. If a pagan was starving and thirsty, does anyone really think he wouldn't shoot someone for a drink and eat them?
Christ went among the pagan unwashed and I'm sure He saw and heard some salty stuff. He thought it no different from some of the people he saw and heard in the Temple. If you are going to witness to dope addicts and whores, don't be surprised to hear an "F" bomb or two. If we witness to choir members, maybe we can live in a "clean, holy, sanctified, world.
