" If this were simply a story about the past, it would be appropriate to write, at the conclusion of Acts 28 as at the conclusion of a film, "The End." But since the story is unfinished, it is more appropriate to conclude it with, "RSVP," like an invitation that awaits a response. This is what Luke demands from us: not satisfied curiosity about the past, but a response here and now. RSVP! "
