A God Box is my spiritual mailbox where I put my prayers. I write them down on a piece of paper, re-read it, fold it up, kiss it (that's the stamp), then put it in the box for God to read. This gets whatever is bothering me, or that I need help with, off my mind and in His hands. Then I sit back and wait for the miraculous changes that take place.
A God Box can be anything. I started with pill bottles, and now use boxes. I can't count the number of prayers I've put in, but I have looked back at some that I've put in. Honestly, I can't find one of them that He hasn't answered.
