We have lived for too long with the arts as the pretty bit around the edge with the reality as a non-artistic thing in the middle. But the world is charged with the grandeur of God. Why should we not celebrate and rejoice in that? And the answer sometimes is because the world is also a messy and nasty and horrible place. And, of course, some artists make a living out of representing the world as a very ugly and wicked and horrible place. And our culture has slid in both directions so that we have got sentimental art on the one hand and brutalist art in the other. And if you want to find sentimental art then, tragically, the church is often a good place to look, as people when they want to paint religious pictures screen out the nasty bits. But genuine art, I believe, takes seriously the fact that the world is full of the glory of God, and that it will be full as the waters cover the sea, and, at present (Rom 8), it is groaning in travail. Genuine art responds to that triple awareness: of what is true (the beauty that is there), of what will be true (the ultimate beauty), and of the pain of the present, and holds them together as the psalms do, and asks why and what and where are we. You can do that in music, and you can do that in painting. And our generation needs us to do that not simply to decorate the gospel but to announce the gospel.
