“Now I pray to God that ye do no evil; not that we should appear approved, but that ye should do that which is honest, though we be as reprobates.”
King James Version (KJV)
13:7 I pray God that ye may do no evil - To give me occasion of showing my apostolical power. I do not desire to appear approved - By miraculously punishing you. But that ye may do that which is good, though we should be as reprobates - Having no occasion to give that proof of our apostleship.
2Co 13:7 Now I pray to God that ye do no evil, etc. If they should do evil, Paul's display of power would show that he was not a reprobate (2Co 13:6), but he prays that their freedom from evil may leave him without that proof. 2Co 13:8,9 show that he desires only to promote the truth.
