“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.”
How can the man and the crowds respond so differently?
They all heard the message from Paul. Paul saw one man had faith and he could see that this man could be healed. The large crowd however were focusing on the miracle and not what they had heard.
The sight of miracles are often more important than the hearing of the message. Preaching is okay but let us get on with the power show. But it is the message that will keep us near the Lord. Faith comes by hearing not seeing.
