Amazon has oodles of awesome Prayers and Affirmations. I was surprised to see them all.
Just think -- God hears and knows all. He also wants you to do the work to find your own style of life... so both Affirmations (repeated over and over until your mind accepts them as fact) and Prayers (letting God know your intentions) is a double incentive to get your life right.
I love affirmations that I can read, remember and repeat all throughout the day. I also love love my audio affirmations... just pure listening while the words sink deeply into my subconscious and take hold, for the greater good.
