The Book of Acts tells the story of how the news about Jesus spread from Jerusalem to Rome.
Because Acts covers such a broad range of places, a map like the one above will help you understand what's going on as you read.
The first half of the book takes place in and around Jerusalem, with much of the action occurring in the temple.
The second half of the book follows the Apostle Paul as he makes disciples in various cites throughout the Roman Empire, such as the city of Ephesus below.
