Here’s a good rule of thumb for commentaries: if Carson or O’Brien wrote it, get it. I’ve always found O’Brien to be extremely knowledgeable, judicious, and fair. This little book is no different. O’Brien explains the fundamental nature of Paul’s mission and how the Apostle could dare claim to have completed his mission in certain parts of the Roman world. He also demonstrates, against scholarly skepticism, that Paul’s ambition should be ours.

"O'Brien's examination of various Pauline texts is detailed and scholarly, and yet, like all good theological scholarship, it can change the way we view Paul's life and writing."
