I don't often repeat posts from one of my blogs to another, but in this case this extract is not only apt for Christians, but also for writers in general. Alan Jacobs, in his book, The Narnian, a biography of C S Lewis as well as an overview of his books, shows how much effective a story is if we start from images rather than 'themes' or theories.
"Everything began with images," he wrote: "a faun carrying an umbrella, a queen on a sledge, a
Or perhaps he could have, but knows that it would have been a dreadful mistake, a giving over of his imaginative life to the "expository demon." What he has to do instead is trust the images that come into his mind - or, more accurately, trust that he is being formed as a Christian in such a way that the images that come to his mind are authentic ones, ones that lie at, or at least near, the centre of his soul. He can do this only if he rejects not only the market-driven questions of modern authors and publishers ("What do children want?") but even the more morally sound question of the Christian apologist ("What do children need?"): "It is better not to ask the questions at all. Let the pictures tell you their own moral. For the moral inherent in them will rise from whatever spiritual roots you have succeeded in striking during the whole course of your life."
This is a terrifying, or liberating, word: liberating in that one need not expose oneself to the sanctimonious drudgery of drawing up lists of Christian truths and hammering out allegories that will meet the desires or needs of children. But terrifying because as those images rise from your mind you discover what you are really made of: you discover whether you are one whose moral and aesthetic responses have been shaped by the Christian narrative or whether you remain a person "without a chest," lacking in true spiritual formation. Trusting the images, you find out who you are.
