For just as my sufferings for Christ are running over the cup, so through Christ my comfort is running over too.

So I am an envoy to represent Christ, because it is through me that God is making His appeal. As one representing Christ I beg you, be reconciled to God.

You look at me and measure me by outward appearances. If anyone is confident in himself that he belongs to Christ, let him have another thought about himself, that just as he belongs to Christ, so do I.

So I most happily boast about my weaknesses, so that the strength of Christ may overshadow me. That is why I take such pleasure in weaknesses, insults, distresses, persecution, and difficulties, which I endure for Christ's sake, for it is when I am consciously weak that I am really strong.

since you demand a proof that Christ is speaking through me. For Christ is not exhibiting weakness toward you but power in you.
