The world that we enter in the book of Acts is the most modern in all the Bible by virtue of its urban identity. Most of the action occurs in the famous cities of the Greco-Roman world, not in the local villages or the countryside. This prevailingly metropolitan world is, moreover, international and cosmopolitan. There is a sense in which the city is vindicated in the history of the early church—not in the sense that the city is mainly good or cordial to the gospel but in the sense that the city is where most people now live and where the influential power structures exist.... It is easy to see that the mission strategy of the early church was to evangelize the city. It is no exaggeration to say that in Acts the church is almost exclusively associated with the city.
