The doctor states that people walk around everyday without corrective lenses, seeing with poor vision. They either do it because of pride, not wanting their weakness to be seen, or because they just do not know any better. These people believe they can see with perfect vision into the spiritual realm because they have had this poor quality of sight their whole life. But can they really? People will not really know how badly they can see until someone who can see better tells them. People squint in the spirit, trying as hard as they can to do the right thing when all along there is an easier way.
