Commenting on Galatians 6:3, “If anyone thinks he is something when he is nothing, he deceives himself.”
Our capacity for self-deception is frightening. It is amazing how blind otherwise brilliant people can be to their own spiritual direction in life. In fact, the more brilliant people are, the more skilled they are at developing rationalizations to deceive themselves and to hide from God. The story of Adam and Eve’s hiding from God behind their skimpy clothes and even skimpier excuses is our common human experience. Paul’s warning needs to be heard, and to be heard often, to warn us against our most brilliant self-delusion.
