2 Corinthians 10:7-11

7Do ye look at what concerns appearance? If any one has confidence in himself that he is of Christ, let him think this again in himself, that even as he [is] of Christ, so also [are] we.

8For and if I should boast even somewhat more abundantly of our authority, which the Lord has given [to us] for building up and not for your overthrowing, I shall not be put to shame;

9that I may not seem as if I was frightening you by letters:

10because his letters, he says, [are] weighty and strong, but his presence in the body weak, and his speech naught.

11Let such a one think this, that such as we are in word by letters [when] absent, such also present in deed.
