Blind to our blindness

"Sin is deceptive. Who does it deceive first? I have no difficulty recognizing the sin of the people around me, but I can be quite unprepared when others point out my sin. Sin deceives ten out of ten people reading this column. Spiritual blindness is not like physical blindness. When you are physically blind, you know you are blind, so you compensate for this significant physical deficit. But spiritually blind people are not only blind, they are also blind to their own blindness. They think they see well. So the spiritually blind person walks around with the delusion that no one has a more accurate view of himself than he does."
