“Superficiality is the curse of our age.” And, so begins this Christian classic, originally published in 1998, by Quaker pastor and spiritual formation pioneer Richard Foster. Hailed by many as the best modern book on Christian spirituality, some even consider it to be in the top 10 most influential Christian books of all time! The book describes traditional spiritual disciplines that have, throughout history, connected people with God and positioned them for transformation. The book is divided into three parts, representing three types of disciplines: inward, outward and corporate disciplines, and is salted with scripture references and historical examples as well. While the book is clarifying and descriptive, it is not written as a practical or experiential guide. Just the same, readers from most Protestant faith traditions will be stirred through Foster’s spiritual passion and prose to discover for themselves, individually or as part of a congregational study or small group, the richness and depth that come through practicing timeless, classical disciplines that move us from the surface into the depths of our life in God.
