Book excerpt: At the end of Romans 11, Paul quotes both Isaiah and Job. As with other New Testament uses of Old Testament texts, this raises several questions. What is the context of these Old Testament passages? How are they used in other Jewish literature? What is Paul's hermeneutical warrant for using them in Romans 11? What theological use does Paul make of them? How, if at all, does their use in Romans 11 contribute to the broader discussion on the use of the Old Testament in the New? In addressing these questions, this book reveals a remarkable typological connection that climaxes in the doxology of Romans 11:33-36, exalting God's incomprehensibility, wisdom, mercy, grace, patience, independence, and sovereignty.
