Psalm 36:1-4

To the choirmaster. Of David, the servant of the LORD. Transgression speaks to the wicked deep in his heart; there is no fear of God before his eyes. For he flatters himself in his own eyes that his iniquity cannot be found out and hated. The words of his mouth are trouble and deceit; he has ceased to act wisely and do good. He plots trouble while on his bed; he sets himself in a way that is not good; he does not reject evil.

Lord, the ability of the unrepentant heart to justify and excuse behavior is an ability without superior. I know, deep in my heart that a course of behavior is wrong, but I can explain and justify why it is appropriate at this time and in these circumstances. I can conveniently forget that You hate evil and abhor sin. I am a master of self-justification and delusion.
