"That's one of the ways in which the self-esteem movement works against the message of the gospel. The prevailing emphasis of our culture is to tell people that what's wrong with them is that they feel bad about themselves. If they will just feel better about themselves, they can be cured of anything.
But the Bible says you'll never feel good about yourself until you learn first to feel bad about yourself. When you realize how bad things really are, then you are in a position to learn how to feel truly good. Then it won't be about you, but about the One who died to forgive your great debt so that you, in turn, can be a debt forgiver to others around you.
Anytime I harbor animosity toward anyone, it is because I have diminished my sense of the debt I owe to the living God."
