Suddenly, Festus shouted, “Paul, you are insane. Too much study has made you crazy!” But Paul replied, “I am not insane, Most Excellent Festus. What I am saying is the sober truth. And King Agrippa knows about these things. I speak boldly, for I am sure these events are all familiar to him, for they were not done in a corner! King Agrippa, do you believe the prophets? I know you do—” Agrippa interrupted him. “Do you think you can persuade me to become a Christian so quickly?” Paul replied, “Whether quickly or not, I pray to God that both you and everyone here in this audience might become the same as I am, except for these chains.”
