For I consider myself not to be one bit inferior to those “super apostles.” [Note: Paul is referring to his opponents there in Corinth who claimed apostolic authority].
I have become foolish [i.e., by my boasting], but you made me do it [i.e., in order to vindicate myself] For I should have been commended by you [i.e., for my effective ministry there in Corinth], because I was not inferior in any way to those “super apostles” [See 11:5], even though I am nothing.
For you have heard about the way I lived in the past, when I was in the Jewish religion, [that is], how I mercilessly persecuted the church of God, making havoc of it.
As far as enthusiasm is concerned, I persecuted the church; as far as being righteous according to the Law of Moses is concerned, I was without just blame.
