The author of the bestselling celebration of discipline explores the great traditions of Christian spirituality and their role in spiritual renewal today. In this landmark work, Foster examines the "streams of living water" –– the six dimensions of faith and practice that define Christian tradition. He lifts up the enduring character of each tradition and shows how a variety of practices, from individual study and retreat to disciplines of service and community, are all essential elements of growth and maturity. Foster examines the unique contributions of each of these traditions and offers as examples the inspiring stories of faithful people whose lives defined each of these "streams."
