Diogenes Allen, professor of philosophy at Princeton Theological Seminary, presents a good case for looking afresh at the process of sanctification "by which we actually begin to become holy." The author believes that one of the most important issues for Christians is, What would it be like actually to live every moment of one's life with an awareness of God? Allen outlines the seven questions which lie behind today's interest in spirituality and then goes on to assess the soulful journeys of Leo Tolstoy, T. S. Eliot, and Simone Weil. He finds in the ascetical teachings of the fourth century desert fathers and mothers insights into what hinders and what helps us on the spiritual path. Allen believes that in addition to reading about God in the scriptures, we ought to read the book of nature for signs of divine grace. It is refreshing to read a Protestant exploration of sanctification. It will speak to laity who are now asking what we can do to improve our spiritual health.
