Paul travels to Jerusalem and greets their believers there, including James who is mentioned by name. The church modeled ethnic hospitality. Paul is arrested for preaching in the temple but is allowed by a soldier to preach publicly. We may be right in what we know, but we don't know everything. Paul illustrates the importance of being able and willing to answer peoples' objections and to make a case to them for being followers of Christ, even though they may not respond positively.
