Summary: Each town Paul visits on his way back to Jerusalem has a church member who warns him not to go or be imprisoned. But he does go and, after some dialogue with the apostles, big surprise--he's arrested.
Response: I think Paul knows he's walking a very fine line talking about Gentiles to Jews. The apostles sounded like they hadn't fully worked out the thought process behind all of this, and of course the crowds are frenzied at this point. I hope I can avoid the knee jerk reaction to God's hand like this and search for His wisdom in the crazy.
