Paul makes a bold claim in this passage: that he consistently acts in ways that cause no offense to others, and that also demonstrate he is a servant of God. He backs up this claim with the evidence of his behavior and character in all sorts of difficult situations. Paul demonstrates that we can and ought to be the same Christian people no matter what happens to us, no matter what our situation is, no matter what our enemies accuse us of or do to us. We should be Christian people day-in, and day-out, no matter what.
