2 Corinthians 10:7-13 King James Version (KJV)
7 Do ye look on things after the outward appearance? if any man trust to himself that he is Christ's, let him of himself think this again, that, as he is Christ's, even so are we Christ's.
8 For though I should boast somewhat more of our authority, which the Lord hath given us for edification, and not for your destruction, I should not be ashamed:
9 That I may not seem as if I would terrify you by letters.
10 For his letters, say they, are weighty and powerful; but his bodily presence is weak, and his speech contemptible.
11 Let such an one think this, that, such as we are in word by letters when we are absent, such will we be also in deed when we are present.
12 For we dare not make ourselves of the number, or compare ourselves with some that commend themselves: but they measuring themselves by themselves, and comparing themselves among themselves, are not wise.
13 But we will not boast of things without our measure, but according to the measure of the rule which God hath distributed to us, a measure to reach even unto you.
