God is creatively present in everyone in every moment whether we are aware of it or not. But when we are in the state of silent gratefulness, we are aware of God's Presence.
~ from THE ETERNAL NOW by Paul Tillich
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.
