2 Corinthians 10
8 Ref For though I might take pride in our authority (which the Lord gave for building you up, and not for your destruction), it will not be a cause of shame to me:
9 Ref That I may not seem to have the desire of causing you fear by my letters.
10 Ref For his letters, they say, have weight and are strong; but in body he is feeble, and his way of talking has little force.
11 Ref Let those who say this keep in mind that, what we are in word by letters when we are away, so will we be in act when we are present.
