We are responsible for the whole of the Covenant, not just the parts we like. As Paul addresses potential questions raised about his statements in chapter 2, he does so through the lens of saying that they will understand his point if they first understand the entirety of the old covenant. This ultimately calls on us to recognize Our Privilege (Access to God),
Our Responsibility (Making Disciples), and Our Hope (Grace winning!) as a holistic approach to understanding our covenant with God.
