I'm not sure where I heard it or why I believed it but when I was in my mid-twenties, a few words changed my approach to and experience of prayer. The words were these: 'Every thought you think is a prayer. Every word you speak is a prayer. Every act in which you engage is a prayer, because the Spirit of God lives in you.' Now, how awesome is that?
