Superb! A veritable reservoir filled with knowledge from many different authoritative sources; includes the complete 'Lectures On Faith' (a must have)and 'The King Follett Discourse' in addition to its insightful commentary and historical context and setting. Easy to read, engaging, difficult to put down! The gospel library isn't complete without it!
If I only had one book to help me understand the Doctrine and Covenants better, this would be it. I've taught EM seminary for several years and love reading the scriptures with a commentary to help enlarge my thinking and understanding. This has so many wonderful insights and it gives great background to the setting in which the revelations were given. It has been great for my understanding of the restoration of so many wonderful gospel truths.
