Self-justification
It is so difficult to take responsibility for our choices and bad beliefs. Saying "I'm sorry" is some of the hardest words to say. We are so good at coming up with reasons to back up why we did what we did. Instead of trying to justify ourselves Jesus invites us to trust Him and let him Justify us.
