O'Brien is senior research fellow in New Testament at Moore Theological College in Sydney, Australia. He is well-known for his major biblical commentaries, including The Letter to the Ephesians (Apollos), and several publications on the subject of mission.
This really is an outstanding study of an often ignored question: Does Paul expect his churches to actively promote the gospel through evangelism? Most Christians would simply assume yes. But generally scholars (and even mission scholars) have raised questions about that assumption. But in this clear and careful study, O'Brien asserts yes, Paul did expect his churches to participate in his mission. Paul's gospel entailed obedience that encompassed all of life, and the very nature of that gospel was to be proclaimed (it was good news, and news is something that is shared). Paul expected his churches to imitate him, and though this certainly entailed ethical imitation, it almost certainly didn't exclude missionary activities, which were so central to Paul's own gospel-saturated existence. And Paul envisioned his churches as "partners" in the gospel, and that not just in support of his far-flung activities but partners in their own cities.
This is a relatively short read, but it repays attention. It delves deeply into the nature of the gospel and of Paul's relationship to his churches. Highly recommended.
I always enjoy reading Peter O’Brien and benefit from his studies. This book no exception. Much to glean as a pastor-teacher, missionary, or student. This brief book is like a J. I. Packer book - much is “packed” into a few pages that are easy to read but profound, calling for further reflection.
