An excellent treatise on spiritual formation. The reader of the audiobook (Grover Gardner) is well suited to the task and easily draws the listener into its contents. A wealth of biblical information on the Kingdom of God and practical illustrations of what it means to be a follower of Jesus Christ. Dallas Willard is a tremendous thinker whose perspective has challenged and encouraged me to pursue spiritual formation and to live out the Christian life the way it was intended. It took me just over a week to finish the CDs while driving to the gym, to work and home. Now that I've finished I find myself listening to it again to take down notes on my computer. The only drawback to the audiobook is not having the notes in front of you when you have an "Aha!" moment. Having said this, I believe I got more out of listening to the book than reading it.
