9 But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.
10 That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.

Paul’s Concern for the Corinthians

11 I have made a fool of myself, but you drove me to it. I ought to have been commended by you, for I am not in the least inferior to the “super-apostles,”a even though I am nothing.
12 I persevered in demonstrating among you the marks of a true apostle, including signs, wonders and miracles.
13 How were you inferior to the other churches, except that I was never a burden to you? Forgive me this wrong!
14 Now I am ready to visit you for the third time, and I will not be a burden to you, because what I want is not your possessions but you. After all, children should not have to save up for their parents, but parents for their children.
15 So I will very gladly spend for you everything I have and expend myself as well. If I love you more, will you love me less?
16 Be that as it may, I have not been a burden to you. Yet, crafty fellow that I am, I caught you by trickery!
17 Did I exploit you through any of the men I sent to you?
18 I urged Titus to go to you and I sent our brother with him. Titus did not exploit you, did he? Did we not walk in the same footsteps by the same Spirit?
19 Have you been thinking all along that we have been defending ourselves to you? We have been speaking in the sight of God as those in Christ; and everything we do, dear friends, is for your strengthening.
