And as he thus made his defense, Festus said with a loud voice, “Paul, you are mad; your great learning is turning you mad.” But Paul said, “I am not mad, most excellent Festus, but I am speaking the sober truth. For the king knows about these things, and to him I speak freely; for I am persuaded that none of these things has escaped his notice, for this was not done in a corner. King Agrippa, do you believe the prophets? I know that you believe.” And Agrippa said to Paul, “In a short time you think to make me a Christian!” And Paul said, “Whether short or long, I would to God that not only you but also all who hear me this day might become such as I am–except for these chains.”
–Acts 26:24-29
A great passage and one that almost uniquely shows us the character and nature of Paul in action. It’s a vivid, visual, cinema-of-the-mind kind of scene.
