Celebration of Discipline by Richard Foster is an excellent starting point for those brave travelers who wish to travel deeper into the forests of Christian Spirituality. Mr. Foster introduces us briefly to what each path holds; all the while showing us practical steps we can take to get us started in each area. This book is exceptional as an introductory not only because it gets us started down the path but because it calls us deeper and deeper in. I wholeheartedly recommend this book to all Christians; and to all those interested in the life lived in and by the Spirit.
