Paul’s third missionary journey, accompanied by various disciples including Timothy and Luke, focused on strengthening and encouraging the early Christian communities he had previously established, as he traveled from Antioch through key locations such as Galatia, Phrygia, Ephesus, Macedonia, Greece, Troas, Miletus, and Jerusalem, preaching the Gospel, performing extraordinary miracles, facing opposition, and providing pastoral care, ultimately solidifying the foundation of the early church despite significant personal risk and challenges.
