A Retreat for Lay People brings together a collection of his conferences preached over a period of fifteen years. His opening topic is Discouragement in Retreat, and he concludes with a reflection on Our Lady's Serenity. In between, Knox addresses the big questions - the fear of death, the problem of suffering, the world to come - but he also explores the little questions that loom large in our daily lives, like minor trials, liberty of spirit in prayer, and the use of God's creatures. Msgr. Knox shapes his collection around the classic Spiritual Exercises of St. Ignatius.
