- Recognize that fantasy is just that: a created world, not the real world. Even if it takes place in a setting meant to resemble our universe, it is still a made-up place, and the author can create whatever rules and truths he wants for that universe.
- Fantasy can be a useful medium for spiritual truth. Jesus often used fantasy - think of the parables He told. Remember the story of the rich man and Lazarus in Abraham's bosom? Scholars debate whether this story really occurred, but if it didn't, it's a superb example of a fantasy in the Bible. (Thanks to Bryan Davis for pointing that out.)
- The reader's job is to discern differences between the fantasy world and the real world, and to choose how to respond to them. A reader should never approach a book written by a fallible human being and unthinkingly accept the message presented in it. He should always be prepared to evaluate the author's intent (for every author has one) and to respond to it from a Biblical perspective (if he is a Christian).
I hope I can teach my students to remember these principles so they won't have to fear fantasy. Anything (aside from Scripture) we take in has potential to harm us or confuse us spiritually, so we must always be alert and thinking as we read, and careful as we write.
