When the crowds saw what Paul had done, they shouted in the Lycaonian language, "The gods have come down to us in human form!" Barnabas they called Zeus, and Paul they called Hermes, because he was the chief speaker. The priest of Zeus, whose temple was just outside the city, brought oxen and garlands to the gates; he and the crowds wanted to offer sacrifice. When the apostles Barnabas and Paul heard of it, they tore their clothes and rushed out into the crowd, shouting, "Friends, why are you doing this? We are mortals just like you, and we bring you good news, that you should turn from these worthless things to the living God, who made the heaven and the earth and the sea and all that is in them." (Acts 14:11-15, NRSV)
When the people saw what Paul had done, they lifted up their voices, saying in the speech of Lycaonia, The gods are come down to us in the likeness of men. And they called Barnabas, Jupiter; and Paul, Mercurius, because he was the chief speaker. Then the priest of Jupiter, which was before their city, brought oxen and garlands unto the gates, and would have done sacrifice with the people. Which when the apostles, Barnabas and Paul, heard of, they rent their clothes, and ran in among the people, crying out, And saying, Sirs, why do ye these things? We also are men of like passions with you, and preach unto you that ye should turn from these vanities unto the living God, which made heaven, and earth, and the sea, and all things that are therein. (Acts 14:11-15, KJV)
Paul and Barnabas are so impressive that the people of Lystra start to worship them as gods. It seems like a pretty sweet deal, but Paul and Barnabas know the truth. Only God is God and you do not want to mess with him.
