10 As surely as the truth of Christ is in me, nobody in the regions of Achaia will stop this boasting of mine.
11 Why? Because I do not love you? God knows I do!
12 And I will keep on doing what I am doing in order to cut the ground from under those who want an opportunity to be considered equal with us in the things they boast about.
13 For such people are false apostles, deceitful workers, masquerading as apostles of Christ.
14 And no wonder, for Satan himself masquerades as an angel of light.
15 It is not surprising, then, if his servants also masquerade as servants of righteousness. Their end will be what their actions deserve.

Paul Boasts About His Sufferings

16 I repeat: Let no one take me for a fool. But if you do, then tolerate me just as you would a fool, so that I may do a little boasting.
17 In this self-confident boasting I am not talking as the Lord would, but as a fool.
18 Since many are boasting in the way the world does, I too will boast.
19 You gladly put up with fools since you are so wise!
20 In fact, you even put up with anyone who enslaves you or exploits you or takes advantage of you or puts on airs or slaps you in the face.
