a world of difference

My original plan fell through.
But my new plan, which is based solely on faith, is sticking a note to the $20 that says "$20 can make a world of difference," and I've underlined the "In God We Trust" on the back of the bill. The plan is to hide it somewhere in a store like WalMart or HyVee, and pray ceaselessly that it finds someone who needs it, or who will pass it on to someone who does.
