As we have seen on the map, Paul and Silas were forbidden from preaching in Asia. If we notice the seven churches to whom St.John wrote the letters in the book of Revelation are located here. There is no competition in the kingdom of God. Though Paul would preach in Ephesus for many months. Now, being called to preach the gospel in Greece which is part of Europe, they land in Philippi. According to one legend, Luke is from Philippi, he studied medicine there. Here in this city, Paul cast out a spirit of Python from the slave girl who was fortune telling and making money for her owners.
