2 Corinthians 10:7-11

7You are looking [only] at the outward appearance of things. If anyone is confident that he is Christ’s, he should reflect and consider this, that just as he is Christ’s, so too are we.

8For even though I boast rather freely about the authority the Lord gave us for building you up and not for destroying you, I will not be ashamed [of the truth],

9nor do I want to seem to be trying to frighten you with my letters;

10for they say, “His letters are weighty and forceful and impressive, but his personal presence is unimpressive and his speech contemptible [of no account].”

11Let such people realize that what we say by word in letters when we are absent, is the same as what we are in action when present.
