I definitely believe there is value. But one must also make sure not to be misled. At one point I was reading bible lessons from my app called YouVersion (it's a very popular Christian app).
Then I started reading this one lesson where the person literally wrote as if it was God giving a message to the reader. That completely turned me off not just from that lesson but from the entire app.
I understand that some people want to deliver more emotional emphasis and personal meaning to their work, so they imagine something that they think God would say about the topic and then write that personal message to the reader. But if God literally didn't convey this to them through a prophecy, then they are making up words that God did not actually say. Nowhere in the lesson did the person attest that God gave them this prophecy, so I believed that they just made it up. And that really bothered me.
Sorry to go off on a tangent, but this topic just reminded me of that incident. Overall though, Christian literature is nice, as are Christian movies. I recently saw the Case for Christ and enjoyed it.
