This book is a powerful and persuasive testimony of Jesus Christ and the reality that he is the Jehovah of the Old Testament and the Messiah that literally and perfectly fulfilled all of what the scriptures (Bible and Book of Mormon) foretold of his mortal ministry, and will yet fulfill all that remains to be fulfilled in his Millennial ministry.
Elder McConkie's writing style is much like his speaking style: bold and confident in the authority of the scriptures and of his authority to proclaim the gospel. He is very thorough (some might say repetitive) in his treatment of the scriptures and the various name-titles and roles that in their totality define the Messiah and his role in the Plan of Salvation. I appreciate his thoroughness and the clarity with which he expounds doctrine. I enjoyed reading the book. There were many times when his peculiar and unique way of wording things would cause me to smile and I could imagine his voice speaking the words aloud in my head as I read. Elder McConkie's writing and testimony of the doctrine is deeply grounded in the scriptures and yet uniquely his at the same time. There is no way you can walk away from this book without knowing absolutely, positively, 100%, that Bruce R. McConkie knew and preached and testified of Christ, and him crucified.
This book, as well as many of Elder McConkie's other sermons and writings, have really enriched my life and I am grateful for them and him. Like all of Bruce R. McConkie's books this book is not light or easy reading. The subject matter is serious, the content is quite dense and rich with truth, and the book is best read slowly with adequate time to ponder, pray, and consider what is written. Some parts are better written than others. Overall, it is a good book and reading it was a valuable part of my education in the restored gospel of Jesus Christ.
2023 reread: rereading the book 5+ years later it is interesting how different parts of the book stood out to me than when I read it the first time. Again, some passages were engaging and powerful and other sections felt a bit dry, slow, and tedious. Still overall a good book that teaches a lot of important and valuable truths.
