If the God of Israel has acted to save his people through Christ, but Israel is not participating in that salvation, how then can this God be considered righteous? Unlocking Romans is directed in large extent toward answering this question in order to illuminate the righteousness of God as revealed in the book of Romans.
The answer here, J. R. Daniel Kirk claims, comes mainly in terms of resurrection. Even if only the most obvious references in Romans are considered — and Kirk certainly delves more deeply than that — the theme of resurrection appears not only in every section of the letter but also at climactic moments of Paul's argument. The network of connections among Jesus' resurrection, Israel's Scriptures, and redefining the people of God serves to affirm God's fidelity to Israel. This, in turn, demonstrates Paul's gospel message to be a witness to the revelation of the righteousness of God.
