The arrogant shall not stand in your sight. You hate all workers of iniquity.
1 Corinthians 4:7

For if I preach the Good News, I have nothing to boast about; for necessity is laid on me; but woe is to me, if I don't preach the Good News.

2 Corinthians 12:5
On behalf of such a one I will boast, but on my own behalf I will not boast, except in my weaknesses.
