Excerpt:
So now I bow my head and try to pray in the mornings, not because I don’t doubt the reality of what I have experienced, but because I do, and with an intensity that, because to once feel the presence of God is to feel His absence all the more acutely, is actually more anguishing and difficult than any “existential anxiety” I have ever known. I go to church on Sundays, not to dispel this doubt but to expend its energy, because faith is not a state of mind but an action in the world, a movement toward the world. How charged this one hour of the week is for me, and how I cherish it, though not one whit more than the hours I have with my wife, with friends, or in solitude, trying to learn how to inhabit time so completely that there might be no distinction between life and belief, attention and devotion.
