To pray is to regain a sense of the mystery that animates all beings, the Divine margin in all attainments. Prayer is our humble answer to the inconceivable surprise of living. It is all we can offer in return for the mystery by which we live... It is so embarrassing to live. How strange we are in the world and how presumptuous our doings. Only one response can maintain us: Gratefulness for witnessing the wonder: for the gift of our unearned right to live, to adore, to fulfill. It is gratefulness which makes the soul great.
I believe that God prays in us and through us, whether we are praying or not (and whether we believe in God or not). So, any prayer on my part is a conscious response to what God is already doing in my life.
