Jonathan Edwards once said: ‘God is glorified not only by His glory’s being seen, but by its being rejoiced in.’ It is not enough to say, ‘I guess he is God, so I have got to knuckle under.’ You have to see his beauty. Glorifying God does not mean obeying him only because you have to. It means to obey him because you want to — because you are attracted to him, because you delight in him. This is what C. S. Lewis grasped and explained so well in his chapter on praising. We need beauty.
