Eph 4"17So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking. 18They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts. 19Having lost all sensitivity, they have given themselves over to sensuality so as to indulge in every kind of impurity, with a continual lust for more. "

Not a feel good scripture but for me it was a convicting one. I never cried so hard in my life as when I realized it was my hard heart that darkened my understanding of God and that in all my life I had by my beliefs of him accused him of being far far less then he was and that I was terribly evil.
