Making All Things New: An Invitation to the Spiritual Life by Henri Nouwen is a short, clean, clear book about how to begin finding the peace of mind to hear the voice of God. The book's epigraph, from Mark, is anchored in Jesus' words: "Do not worry." Nouwen acknowledges that worry is so ingrained in many people's daily lives that it seems to be an integral part of positive achievement and self-protection. Yet he explains, with devastating directness, the destructive effects of busy-ness and its attendant habit of worrying, then shows how Jesus responds to these worries, and finally describes some disciplines that "can cause our worries slowly to lose their grip on us, and which can thus allow the Spirit of God to do his recreating work." Nouwen's voice sounds like that of the mentor or spiritual director that many people have always wished for: his authority stems from a talent for realistic comfort rather than forceful coercion. So when he writes the following words, it's eminently possible to believe him.
