I'm a Christian too, but I would never describe my novels as "Christian". Nor are they for "Christian" readers. They are for all readers (or at least, readers who like mystery horror-thrillers and the like).

I don't believe in deliberately inserting Christian messages (or indeed any messages) into stories. It makes them preachy. Instead, I believe in simply telling a good story with no agenda whatsoever. I find that what is important to me is then inherent in the text without it being preachy. This is a principle Christian filmmakers would do well to heed, in my not remotely humble opinion.

I wish you all the very best in your filmmaking endeavours. :)
