Over the course of his life, Catholic priest Henri Nouwen wrote thousands of letters to friends, parishioners, students, and readers of his work all around the world. Believing that a thoughtful letter written in love could truly change someone's life, Nouwen corresponded in English, Dutch, German, French, and Spanish, and took great care to archive the correspondence. Spanning the Dutch theologian's career, the 100 letters collected here are poignant, witty, and rich in spiritual insights, highlighting a number themes that emerged in Nouwen's work over the years, including vocation, solitude, prayer, and perseverance in difficult times.
