2 Corinthians 1:12; 2 Corinthians 2:6; 2 Corinthians 11:10

12 For our rejoicing is this, the testimony of our conscience, that in simplicity and godly sincerity, not with fleshly wisdom, but by the grace of God, we have had our conversation in the world, and more abundantly to you-ward.
6 Sufficient to such a man is this punishment, which was inflicted of many.
10 As the truth of Christ is in me , no man shall stop me of this boasting in the regions of Achaia.
