Now I pray to God that you do no evil; not that we should appear approved, but that you should do that which is honest, though we be as failures.
All Commentaries on 2 Corinthians 13:7 Go To 2 Corinthians 13
Paul is praying that he and his colleagues will be humbled, as it were, by seeing the Corinthians so well behaved that he will not dare rebuke them. If they are humbled in this way, they will appear to be false. It is when they judge sinners with the authority granted to them that they are seen to be approved as genuine by God. If then there are no people for them to judge, it looks as if they have been proved false through the lessening of their authority. Commentary on Paul’s Epistles.
