The opening paragraph of the book of Acts declares, clearly and solidly, that it is a sequel. There has been a previous book, and this one continues the story. It even suggests a kind of title: “The Deeds and Teachings of King Jesus, Part Two”. At first sight this is a strange title, since Jesus himself only appears during the first nine verses of the first chapter. But Luke, whose first volume we know as the Gospel which bears his name, is telling us in his opening sentence one of the most important things about this second book. It is all about what Jesus is continuing to do and to teach.
