The book was good, but not great. Maybe it has to do with expectations. Turns out, the book is 50 short essays on various theological constructs, a sort of "systematic theology lite", if you will. Nothing wrong with that, of course, but the book would be more suited to perhaps a daily devotional, with time given to studying all the inserted scripture references. Ferguson does not go too deep on any particular topic, so it is up to the reader to continue the study with a study Bible and a good set of commentaries.
I thought the first third of the book was particularly strong, especially part I, which focuses on Christ made flesh, and the implications of that mind-boggling event. But the book cooled down for me after that. The book is highly rated on both Goodreads and Amazon, so it is possible that I was simply disappointed in the presentation - based on the title and tagline, I was hoping for a deeper and more drawn-out thesis on living the gospel-centered life. So, take my review with a grain of salt.
Ferguson also interjects old hymns into most chapters when the lyrics coincide with the point he is making. This may or may not appeal to you, as most of them are written in older prose.
