The Great Omissionby Dallas Willard
Like everything else written by Dallas Willard, I highly recommend this book. I'd like every leader in my church to read it and take it to heart.
"Christian spiritual formation is the redemptive process of forming the inner human world so that it takes on the character of the inner being of Christ himself. In the degree to which it is successful, the outer life of the individual becomes a natural expression or outflow of the character and teachings of Jesus. But the external manifestation of Christ-likeness is not the focus of the process, and when it is made the main emphasis the process will be defeated, falling into crushing legalisms and parochialisms." (p. 105)
