Ordering Your Private World by Gordon MacDonald
Gordon MacDonald talks about the cultivation of one's inner spiritual life he calls it ordering your private world. We have come to believe in Church culture that a busy active person in Christian ministry is a spiritual person and this is not always the truth. A public person can be a person who has not developed his inner spiritual life.
The book looks at our inner motivations, how we manage our time, the life of the mind, spiritual growth, and how we are restored.
This book has been around since the 80's but if you haven't read it yet I highly recommend it.
