To act out the principle of turning prayers over to God, we took a paper bag, wrote "God" on it, and taped it up high on the back of our kitchen door. As I prayed about matters such as my career, my role as a father, my abilities to be a good husband, I would write down each concern on a piece of paper. Then those pieces of paper would go in the bag. The rule was that if you start worrying about a matter of prayer that you've turned over to God, you have to climb up on a chair and fish it out of the bag. I don't want to admit how much time I spent sifting through those scraps of paper.
