2 Corinthians 10:7-11
10:7 You are looking at outward appearances. If anyone is confident that he belongs to Christ, he should reflect on this again: Just as he himself belongs to Christ, so too do we.
10:8 For if I boast somewhat more about our authority that the Lord gave us for building you up and not for tearing you down, I will not be ashamed of doing so.
10:9 I do not want to seem as though I am trying to terrify you with my letters,
10:10 because some say, “His letters are weighty and forceful, but his physical presence is weak and his speech is of no account.”
10:11 Let such a person consider this: What we say by letters when we are absent, we also are in actions when we are present.
