Deeply conversant in the full range of questions and interpretations of the letter, Jewett's commentary explores the crucial and controverted passages that have always animated studies of Romans.
Jewett also incorporates the exciting new insights from archaeology of the city of Rome, social history of early Christianity,social-scientific work on early Christianity, and the interpretation and reception of Paul's letter through the ages.

Breaking free from abstract approaches that defend traditional theologies, Jewett shows that the entire letter aims to elicit support for Paul's forthcoming mission to the barbarians in Spain. His work specifically focuses on Paul's missionary plans and how they figure in the letter, on Paul's critical and constructive tack with the Roman community, and finally and especially on how Paul's letter reframes the entire system of honor and shame as it informed life in the Roman Empire at the time. The latter remains a pertinent message today. The first commentary to interpret Romans within the imperial context as well as in the light of the situation in Spain.

Paul's letter to the Romans has been called "the quintessence and perfection of saving doctrine". Perhaps the most challenging and thoroughly doctrinal book of the entire New Testament, Romans deals with many issues that are basic to Christian theology and practice.
Douglas Moo provides a superb study of Paul's letter to the Roman Christians and restates the enduring message of Romans for Christians today. Originally written for the Wycliffe Exegetical Commentary series, this work has been substantially expanded and adapted for the NICNT series; it now treats the entire book of Romans rather than the first half.
Based on the English text but bringing into the discussion the underlying Greek at every point, this commentary focuses both on theological meaning and on contemporary significance.
Moo makes a contribution to the continuing debate regarding Paul's teaching on such issues as Jewish law and the relationship between the Jews and Gentiles in the people of God. He also critically interacts with "the new perspective on Paul", highlights Romans's emphasis on "practical divinity", and traces the theme of gospel throughout the epistle.
