Richard J. Foster’s Celebration of The Path to Spiritual Growth is hailed by many as the best modern book on Christian spirituality with millions of copies sold since its original publication in 1978.

In Celebration of Discipline, Foster explores the "classic Disciplines," or central spiritual practices, of the Christian faith to show how each of these areas contribute to a balanced spiritual life.

Foster, the bestselling author of several books (Prayer and Streams of Living Water) and intrachurch movement founder of Renovaré, helps motivate Christians everywhere to embark on a journey of prayer and spiritual growth.
