Some primitive tribes paint their faces so that their gods cannot recognize them when they kill. We may smile at such absurdity, but modern man is no different. He thinks that God, who made his eyes, cannot see his sin. But it is the sinner, not God, who is blind. See Psa. 94:7–11
Job 24:15The eye of the adulterer waits for the twilight, Saying, ‘No eye will see me’; And he disguises his face.
