For everything [i.e., that we have experienced. See verses 8-12] is for your sakes so that [God's] unearned favor, being extended to so many, [in bringing them salvation through Paul's ministry] may result in much thanksgiving in praise to God.

For even though I caused you sorrow by my letter [Note: Paul's writing of I Corinthians to correct abuses at Corinth apparently produced sorrow for their wrongdoing], I do not regret it, though I did regret it. [For] I see that my letter hurt you, though only for a short time.

And he has great affection for you when he remembers how obedient all of you were [i.e., obedient to his or Paul's instructions to the church], and how you welcomed him with fear and trembling [i.e., with a respectful, submissive spirit].

You people are looking [merely] at the appearance of things [or, "You should look at what is obvious!" In either case, it suggests they were misjudging Paul's ministry]. If any person is confident within himself that he belongs to Christ, he should reflect on this again: We are just as much Christ's [servants] as he is.

But what I am doing, I will continue to do, so that I can cut off the opportunity from those who want an occasion [to receive financial support for themselves because of my example of receiving it]. They want to boast [that they are preaching] on the same terms as I do. [Note: Paul's argument seems to be that one reason for his foregoing financial support was so those "super apostles" in Corinth (see verse 5) would not be able to use his example to wrongfully exact financial support from the church].

Are they [i.e., Paul's opponents there in Corinth] Hebrews? So am I. Are they Israelites? So am I. Are they descendants of Abraham? So am I.
