In his book Blue Like Jazz, Donald Miller writes about a Christmas Eve when his view of God was changed, and how that affected his perspective on everything else.

For my mother that year I had purchased a shabby Christmas gift—a book, the contents of which she would never be interested in. I had had a sum of money with which to buy presents, and the majority of it I used to buy fishing equipment….

I drifted in and out of anxious sleep, and this is when it occurred to me that the gift I had purchased for my mother was bought with the petty change left after I had pleased myself. I realized I had set the happiness of my mother beyond my own material desires.

This was a different sort of guilt from anything I had previously experienced. It was a heavy guilt, not the sort of guilt that I could do anything about. It was a haunting feeling, the sort of sensation you get when you wonder whether you are two people, the other of which does things you can't explain, bad and terrible things.

The guilt was so heavy that I fell out of bed onto my knees and begged, not a slot-machine God, but a living, feeling God, to stop the pain. I crawled out of my room and into the hallway by my mother's door and lay on my elbows and face for an hour or so, going sometimes to sleep, before finally the burden lifted and I was able to return to my room.

We opened the rest of our gifts the next morning, and I was pleased to receive what I did, but when my mother opened her silly book, I asked her forgiveness, saying how much I wished I had done more. She, of course, pretended to enjoy the gift, saying how she wanted to know about the subject.
