2 Corinthians 1:12-14 - Paul's Clear Conscience
12 For our boasting is this, the testimony of our conscience, that in holiness and purity of God, not in carnal wisdom, but in the grace of God, we have sojourned in the world, and especially towards you. 13 For we do not write other things to you, but those things which you read and know, and I hope that you will know them perfectly: 14 as you have also known us in part, because we are your glorying, as you ours in the day of the Lord Jesus.
