In his beautiful book, "I Shall Not Want," Robert Ketchum tells of a Sunday School teacher who asked her group of children if anyone could quote the entire 23rd Psalm. A golden-haired, four-and-a-half-year-old girl was among those who raised their hands. A bit skeptical, the teacher asked if she could really quote the entire psalm.
The little girl came to the front of the room, faced the class, made a perky little bow, and said, "The Lord is my shepherd, that's all I want."
She bowed again and went and sat down.
That may well be the greatest interpretation of the 23rd Psalm ever heard.
