Paul entered Asia but the Holy Spirit prevented him from evangelizing. He has a vision of a Macedonian man encouraging him to come to Macedonia. Paul makes his way to Phillipi, a major city in Macedonia. Phillipi is a rich port city with access to farmland and gold. It is also the site of the Battle of Philippi, where Octavius Caesar and Marc Antony defeats the Roman Republic. Afterwards it becomes a home for Roman veterans to retire. Philippi also had easy access via the Egnatian Way to many other cities. However it was far outside of Christianity’s reach thus far.
Note: A map of Paul’s missionary journeys is frequently referred to in this episode and may be useful.
