The Path To Spiritual Growth by: Richard Foster Arguably the most established contemporary spiritual classic by our most profound living religious writer. This timeless classic has helped well over a million people discover a richer spiritual life infused with joy, peace and a deeper understanding of God. The book explores the ‘classic disciplines’ of Christian faith: the inward disciplines of meditation, prayer, fasting, and study; the outward disciplines of simplicity, solitude, submission and service and the corporate disciplines of confession, worship, guidance and celebration.
