Some of us have to be called out of a nice, calm and secure existence to make it to heaven.
St. Paul was called out of Judah and was sent by God to many countries of the world. The Romans had created the Pax Romana, a time of relative peace, and had created some of the best roads in the world, some lasting to this day.
Getting about to preach the Gospel and teach was planned by God, using the engineering and military expertise of the Romans to facilitate the spread of Catholicism. I list the places to where he went, omitting the duplicate visits.
St. Paul traveled to Damascus, Jerusalem, Antioch, which was in Syria, Seleucia, Cyprus, Salamis, Paphos, Perga, Antioch in Pisidia. He went to Iconium, Attalia, Cilicia, Derbe and Lystra, Phrygia and Galatia. Then, he went from Mysia to Troas, the island of Samothracia, and then to Neapolis in Macedonia. After that, Paul went to Philippi, Amphipolis, Appolonia, and Thessalonica.
He then traveled to Berea, Achaia to Athens, and Corinth.
Paul then traveled to Cenchrea, Ephesus, Caesarea, Troas and Macedonia. Then, he went to Achaia, Assos, Mitylene, Chios, Samos, Trogylium, and Miletus. Then he went to Coos, Rhodes, Patara, and Tyre. After that, he traveled to Ptolemais. He continued to Sidon, Myra, Lasea, and Malta.
Then, Paul went to Syracuse, to Rhegium, Puteoli, and Rome.
