This book is one I will reread over and over and am using for a men's book discussion group. Packer is brilliant, very efficient with words and uses numerous book and scriptural references. I've read more bible than Packer going through this book. One flag: I think making hyperlinks to all the references overwhelmed the Logos employees as I have reported several errors. Though it can be bothersome, I encourage every reader of the Logos version to join with the Logos staff in the noble endeavor of helping those that read after us by reporting the hyperlink errors. This book is worth the effort.
