Did people during the time of Jesus really believe in Zeus?


When the crowd 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 bulls and wreaths to the city gates because he and the crowd wanted to offer sacrifices to them. Acts 14:11-13
            They did.  Zeus was a Greek God.  The Romans had a similar counterpart known as Jupiter.  When Paul and Barnabas were in Lystra, which would be Turkey today, a crowd thought that Zeus (the main Greek god) and Hermes (the messenger god known as Mercury to the Romans) had come down to do miracles.  They worshipped Paul and Barnabas for healing a man who couldn’t walk.  There was obviously a worship system in place for these gods since a priest lived in the town.  It doesn’t appear the Greek and Roman god system was much competition for Christianity, but it was around.
