Most incompetent people don't know they are incompetent. In fact, researcher Dr. David A. Dunning of Cornell University reports that people who are incompetent are more confident of their abilities than competent people. Dunning and his associate Justin Krueger believe that skills required for competence are the same skills necessary to recognize that ability.

Krueger writes in the Journal of Personality and Social Psychology, "Not only do [incompetent people] reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the ability to realize it."

That is the way we are spiritually without Christ. Our sin not only separates us from God, it blinds us to our predicament.
