“I am a master at identifying sin. I might be tempted to brag about that fact, except for this: While I’m a master at identifying the sin in other people, I’m a mere novice at identifying the sin in myself. And I don’t think I’m the only one. There seems to be something deeply embedded in sinful humanity that gives us the ability to spot the sin in others but to ignore it in ourselves. We can provide a thorough accounting of someone else’s flaws, but often only a cursory account of our own.”
