In his essay "On Fairy-Stories", Tolkien discusses the Christian, their Gospel (or Evangelium), and the role of creativity between the two. Really, the essay is more of a call to engage the art world, specifically in creating fantasy stories. I get that you might be reading this and thinking that this isn't you... that you don't have that "gift". Speaking into this self-depricating view, while simultaneously promoting every person's innate ability, he writes
So why apply it? He continues
So you might now be asking "why escape?" and "Isn't that idolatry?" Yes. if handled poorly. But that is not Tolkien's point. To this he concludes:
We are all journeying, lost within a broken wilderness. And we do so while meeting others along the way. We may even be blessed to see that there is a way out - we may find reprieve. But not all of those we meet have realized this hope yet. So, continue to imagine, create, and write for the sake of helping your fellow man transcend this fallen world, and glimpse the wholeness of the world that is more true.
