We have a Book of Mormon in our car. It's been there for years, ever since a student gave it to Will after inscribing it with a sweet message imploring him to read the book. It is stored in the little pocket behind the driver's seat and Will keeps dollar bills in it, for emergencies.
I had one such emergency at Costco when I discovered that I was absolutely starving and needed a slice of pizza and a Coke from the concession stand. Alas, I had no cash and the stand does not take cards.
Aha! I remembered the Book of Mormon in the car seat pocket, pulled it out, and flipped through the pages to find three crisp dollar bills--just enough for a slice and a soda.
Jesus saves, friends.
(I hope the fact that we keep dollars in our Book of Mormon isn't, you know, offensive. We're not Mormon, but there's a definite reverence for the book which has saved us on many an occasion.)
