Here's an article that every pastor and theologian should read and think through: Leland Ryken's "'With Many Such Parables': Imagination as a Means of Grace."

It begins as follows: "The aim of this article is to explore a heresy that rules vast segments of evangelical Christianity. That heresy is to defend a neglect of the imagination and the arts on the ground that believers must be busy in God's work, assuming that God's work is never artistic. Yet the Bible itself, to say nothing of the creation in which humankind lives, shows that God's work is partly artistic."
