I. Howard Marshall offers commentary on the book of Acts, showing how it functions as a history of the early church, as a literary work, as the sequel to the Gospel of Luke, and as theology. Luke's purposes are varied: he writes with pastoral concern, he shows that the essential task of the church is mission, and he makes plain that God does not accept racial discrimination among his people.

Marshall was one of the foremost Lukan scholars of the twentieth century, and his handling of Acts keeps the historical questions and the theological ones in the same frame rather than treating them as rivals. The Tyndale format gives a concise introduction followed by section-by-section exposition, which suits the preacher working through Acts as well as the student meeting it for the first time.
