Liturgy pulls our prayers out of the tiresome business of looking after ourselves and into the exhilarating enterprise of seeing and participating in what God is doing. We are drawn into a large generosity where everyone is getting and receiving, offering and praising. We are drawn to the place where people are being loved and where they love us. We are deepened into the practice of humanity in covenant with God that goes both beneath and beyond our self-defined religious desire. We are put beside people who help us and whom we can help. Liturgy breaks us out of the isolation of ego and emotion where we are cut off from the large winds and landscapes of grace. God wants us outside the walls that quarantine us in our ego-sickness; he pulls us into the great dance of grace in which we find ourselves moving rhythmically and joyfully with partner after partner. Selah - indeed.
