As you visit the rock forest of Meteora ("in the heavens above") in western Thessaly, imagine the Apostle Paul walking that treacherous terrain on his missionary journey. The breathtaking Byzantine monasteries are spectacularly perched on soaring, sheer-sided gray sandstone pillars. In the 13th century, monks sought refuge in cliff-side caves before fleeing higher to build the original wooden shelters that later became these monasteries. After a monastery tour, travel to scenic Delphi, the religious center of the ancient Greek world and marked by the conical stone called the omphalos ("navel"). Walk the Sacra Via to the Athenian Treasury, Theatre, and the Temple of Apollo, where the oracle performed her prophetic rituals. As you consider the incredible amount of pagan influence just in Delphi alone, you will gain a new appreciation for the tremendous spiritual opposition the Apostle Paul faced in preaching the Gospel of Christ here. The museum has many ancient treasures, including the fifth-century bronzed charioteer so detailed you can see his eyelashes. Continue to Athens overnight.

Tour the city of Corinth, where the Apostle Paul met fellow tentmakers Aquila and Priscilla and received a vision from the Lord saying, "I am with thee, and no man shall set on thee to hurt thee: for I have many people in this city" (Acts 18: 10). As Paul spoke, Crispus (chief ruler of the synagogue) and many others believed and were baptized (Acts 18:8), establishing the church at Corinth to whom Paul later wrote his two epistles. Discover the archaeological museum, marketplace, and temples. As you walk among the ruins, stand on the Bema, where the Apostle Paul stood before Gallio to face charges brought against him by the Jews. Stop briefly at the port town of Cenchreae, from which Paul later departed for Syria (Acts 18: 12-18). Return to Athens for dinner and overnight.
