This book is for a select audience.
1. They believe or at least admit the possibility of divine authorship of the Old Testament.
2. They care enough about the mechanics of interpretation to do a fairly deep dive into communication theory.
But if you are someone who cares about intellectual integrity and is at least somewhat dissatisfied with grammatical-cultural-historical-literary approaches to interpretation, this is a significant and arguably helpful perspective.
This book does not contain very many heart warming devotional passages, and unless you are already well-versed in relevance theory will prove challenging, but when I look back on the quarantine of 2020, I will be proud to tell my grandchildren that one of the things I did while I was restricted was to purchase and read this book.
