There is much in this book that is great, beautiful, and wonderful exposition. But there are some very strong disagreements I have. I think she does a great job pointing out the role of the Law and the Prophet and the necessity of the Old Testament in order to fully understand humanity, God, identity, and much more. I agree with her critiques of modern (especially Western Cultural) preaching around the Prophets and the Old Testament. The twisting, misunderstanding, ignorance of, and poor application of both. Chapter 6 itself could easily be it's own sermon or series of sermons it was so wonderful!
However it is worth noting my strong disagreement with her on the historicity intended in Genesis 1-11, I do think Adam and Eve were literal and that we did partake in their fall with Adam as our federal head which the New Testament is abundantly clear on as well as the Old. I do think the Prophets were lambasting the people for more than simply their lack of faith, trust, and love in God which led to their disobedience, but the disobedience itself as well. Her pitting of God's love against His wrath/judgement (which is an all too common mistake in our time one I myself was once guilt of). Her view that Wisdom 8 isn't talking about the Trinity is another strong area of disagreement.
It is a good book and one worth reading if you don't have another resource that is this in depth on the topic at hand, but I think there are much better works (especially among the Church fathers) on this issue even if they don't speak nearly as well into the modern errors of our time.
