I listened to this classic in the car this year. Although I still struggle with the medium of audiobooks (see here and here), and as such find it hard to write a substantive review as I have retained far less of the book than if I had read it with highlighter in hand, it was easy to see why this book is such a classic. Packer unpacks (see what I did there) deep, breathtaking Truth about God in an accessible and engaging way, and in a way that doesn't just leave the reader (or hearer) feeling more knowledgable about God, but actually points the heart and mind to worship God.
I will be returning to this book often, next time in writing.
