From my reading . . .
Artists, even those who are Christian, are fallen people observing a fallen world. Because the world is fallen we have to take notice of its brokenness and acknowledge it in our work. Because we ourselves are fallen we have to monitor our perceptions, because we know that they can be distorted by sin. We should hesitate before calling anything we do Christian art because we don’t know how much of our own pride, selfishness or ignorance has polluted our vision.
