2 Corinthians 10:7-11

7Look at what is before your eyes. If anyone is confident in himself that he belongs to Messiah, let him reconsider that just as he belongs to Messiah, so also do we.

8For even if I boast a little more about our authority—which the Lord gave for building you up and not for tearing you down—I will not be put to shame.

9Not that I would try to terrify you by my letters—

10for they say, “His letters are weighty and strong, but his presence in person is weak and his speech of no account.”

11Let such a person consider this, that what we are in word through letters when we are absent, we also are in action when we are present.
