2 Corinthians 6:3; 2 Corinthians 6:10; 2 Corinthians 7:9; 2 Corinthians 11:5

3 giving no cause for offense in anything, so that the ministry will not be discredited,
10 as sorrowful yet always rejoicing, as poor yet making many rich, as having nothing yet possessing all things.
9 I now rejoice, not that you were made sorrowful, but that you were made sorrowful to the point of repentance; for you were made sorrowful according to the will of God, so that you might not suffer loss in anything through us.
5 For I consider myself not in the least inferior to the most eminent apostles.
