I thought this was brilliant! Not only does it get you to THINK more about your prayers, but it helps you remember what you prayed for and in turn will help you recognize when God ANSWERS your prayers. I've been guilty of praying for things, then just going about my day not noticing or even expecting my prayers to be answered. I've been trying harder to NOTICE the many miracles in my everyday. Trying to recognize every blessing and allow God to guide me in doing what HE wants me to do.
Affirmations can be considered prayers, but the only difference is with prayers, we are giving God the glory and taking away any assumption that we did it ourselves. Everything good comes from God, even our abilities to overcome and accomplish great things. He's with us every step of the way.
