This is a great book giving a detailed and extensive Bible-wide exploration of the development of God’s unfolding covenant with mankind. Williamson does a great job of turning over pretty much every stone, looking at basically every passage where “covenant” is explicitly or implicitly mentioned. This impressively provides the reader with a fully-orbed map of this theological concept. He also really nicely explains the differences between each covenant, but also how they are always developing and heading in the same direction. To be honest, I think a lot of this book went over my head. That’s because Williamson is highly intellectual and an expert in the field, and I, on the other hand, am certainly not and I probably wasn’t quite ready for this book. I feel that a conclusion chapter would have been really helpful for me to tie all the covenants together. Would I recommend it? Yes, but only if you are interested in learning more about this topic, because this is an in-depth, academic read, which requires time and attention.
