Humility has long been my favorite of the virtues. Perhaps because it's the one that seems the hardest to obtain? This book on humility might be my new favorite—or perhaps tied with The Freedom of Self Forgetfulness by Timothy Keller.
The biggest difference I see between the two is thoroughness and more discussion of self-reflection in Humble Roots, a concept that can get easily lost in being self-forgetful. (Although, in defense of Keller, he was not writing an exhaustive book on humility.) I also am a huge fan of the discussion of self-deprecation being seen as a vice and the cure as humility. That is another reason I love this particular virtue so much as I struggled with self-deprecation in my teen years.
Anderson’s metaphors were careful, biblical, and easily applied. Also I loved her use of both philosophy and theology which I find is rare in evangelical circles.
I would highly recommend this to anyone looking for a deeper understanding of humility.
