He breaks following Christ into 4 areas and go into depth in each one with stories and truth that inspire and inform. He starts with humility and then moves through community, simplicity, submission and ends with brokenness.
It's nothing fancy. Reading it on the heals of Becoming the Answer to our Prayers was probably a God-thing as they dovetailed nicely. I can't recommend this book enough. Only a 152 pages, it's short, sweet and delightful to eat (plenty of salt in this one).
