if you don't have doubts you're either kidding yourself or asleep. Doubts are the ants-in-the-pants of faith. They keep it alive and moving. - Frederick Buechner

From the essay on Love, in which he describes as a wilderness experience his daily visits with his wife to a hospital 3,000 miles from home in a strange city, where someone he loves is in danger of dying.
“When the worst finally happens, or almost happens, a kind of peace comes. I had passed beyond grief, beyond terror, all but beyond hope, and it was thee, in that wilderness, that for the first time in my life I caught sight of something of what it must be like to love God truly. It was only a glimpse, but it was like stumbling on fresh water in the desert, like remembering something so huge and extraordinary that my memory had been unable to contain it. Though God was nowhere to be clearly seen, nowhere to be clearly heard, I had to be near him — even in the elevator riding up to her floor, even walking down the corridor to the one door among all those doors that had her name taped on it. I loved him because there was nothing else left. I loved him because he seemed to have made himself as helpless in his might as I was in my helplessness.

We try so hard as Christians. We think such long thoughts, manipulate such long words, and both listen to and preach such long sermons. Each one of us somewhere, somehow, has known, if only for a moment or so, something of what it is to feel the shattering love of God, and once that has happened, we can never rest easy again for trying somehow to set that love forth not only in words, myriads of words, but in our lives themselves.

He [Jesus] speaks in parables, and though we have approached these parables reverentially all these many years and have heard them expounded as grave and reverent vehicles of holy truth, I suspect that many if not all of them were originally not grave at all but were antic, comic, often more than just a little shocking.
