This was a grab from the pile of books we get from publishers at work, and it was a great look at a variety of spiritual disciplines and how they can help us grow and mature in our faith. I wasn't overly obsessed with it and found myself skipping ahead at a few points, but it's a great overview book (he admittedly says SO much more could be written about each discipline, but that his intention wasn't to do deep dives into all of them) and one I would definitely pass along to friends wanting to get intentional about the way they live out their faith.
