I ask myself when I feel God’s pleasure, in the Eric Liddell sense, and it happens—seldom, to be sure, but it happens—when I’ve just broken through to a song after hours of effort, days of thinking, months of circling the song like an airplane low on fuel, searching desperately for the runway. Then I feel my own pleasure, too, a runner’s high, a rush of adrenaline. I literally tremble. There is no proper response but gratitude.
