2 Corinthians 10:2, 6, 8-9

I ask that when I am present I need not be bold with the confidence with which I propose to be courageous against some, who regard us as if we walked according to the flesh.

and we are ready to punish all disobedience, whenever your obedience is complete.

For even if I boast somewhat further about our authority, which the Lord gave for building you up and not for destroying you, I will not be put to shame, for I do not wish to seem as if I would terrify you by my letters.
