Fr John Edwards offers us answers to the ancient questions about God's existence and His will. In exploring the process known as 'discernment of spirits' he draws on the Spiritual Exercises of St Ignatius of Loyola.One of the merits of this useful book is that it takes seriously what we are as human beings, created by God, and shows how living in Christ enables us to express our true humanity in the way we live. Its practical advice will be especially useful to priests called to guide others in the spiritual life, while it will also give great help to those who are perplexed about their beliefs. In both respects Fr John Edwards shows himself aware of the way in which people are affected by contemporary secular thought and its inadequacy to take account of human nature and its real needs.'It is good to have these important truths put before us in a clear and uncluttered way. I welcome Fr Edwards' approach warmly'. Archbishop Mario Conti'Having made a thirty-day retreat some years ago, I recognise in Fr Edwards' book the pure well-spring of Jesuit spirituality. If you thirst for water of the spirit, you will find here an oasis in the desert. I thoroughly recommend it.' Sr Briege McKenna OSC
