2 Corinthians 10:7-11

7You 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.

8For 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.

9I do not want to seem as though I am trying to terrify you with my letters,

10because some say, “His letters are weighty and forceful, but his physical presence is weak and his speech is of no account.”

11Let such a person consider this: What we say by letters when we are absent, we also are in actions when we are present.
