Jesus confronts natural and spiritual blindness. He cures the blind man and in the process the spiritual blindness of the man by introducing the Savior of the World to Him. Up close and personal!
Meanwhile, there were others who thought they could see but were so blind they failed to recognize the Messiah standing before them. Their pride blinded them to the Light of the World and they continued in darkness. Therefore, it is paramount we humble ourselves for only in that state will we see the Truth which has been shined on us.
