Cosgrove's interpretation of Paul's letter to the Romans is a study of the identity and destiny of Israel. He realizes that language allows for many possible interpretations, saying that Bible readers can never know for certain Paul's intent, but they can establish a range of interpretations by taking the book in various contexts. Cosgrove also examines Israel as symbol and metaphor, nationalism and national differentiation in Pauline perspective, and the politics of God according to Romans 11.
