Paul’s missionary journeys, recorded in the Book of Acts, consisted of three main journeys from Antioch, where he spread the Gospel and planted churches in Asia Minor and Europe, facing persecution but also converting many, including Gentiles. Key locations included Cyprus, Pisidian Antioch, Lystra, and Ephesus, where he established significant Christian communities and wrote letters of instruction to them. His journeys aimed to proclaim Jesus as the Messiah and the only true God, establishing churches where people were united regardless of background.
