My granddaughter Lily sometimes has racing thoughts that keep her awake at night. A few nights ago, she could not sleep, so I went to see what she needed. She was just anxious and agitated so I asked if I could read to her. When I asked which book she said, "The Bible."
I got out a Bible and read from Matthew 5, and after that a psalm. In a few minutes she was asleep, and stayed that way until morning.
