Celebration of Discipline could be described as a book in recipe form about spiritual growth. Within, Foster outlines twelve spiritual disciplines under three headings: (1) The Inward Disciplines (Meditation, Prayer, Fasting, and Study), (2) The Outward Disciplines (Simplicity, Solitude, Submission, and Service), and (3) The Corporate Disciplines (Confession, Worship, Guidance, and Celebration). These are basic disciplines of the Christian faith which are easy to list but much more difficult to put into practice. A disciple is a follower and a disciple of Christ is one who follows Christ. These principles are presented in such a way to facilitate growth as a disciple. There is little doubt in my mind that Foster has provided his readers with a challenge to get serious about one’s relationship with the Lord. This is the takeaway for me from the book which I believe will help solidify my own practice of the disciplines. However, there are a few concerns with regard to his interpretation of Scripture and perhaps some inclusion of outside sources. This might be from his Quaker background. Even still this little book is a must read in my opinion and provides a simplistic approach to applying the disciplines of the Christian faith. Well worth the study and should be revisited often as one continues the journey.
