Too often we look at others and pass judgment that they brought on themselves their problems. The disciples upon seeing the blind man asked "Master, who did sin, this man, or his parents, that he was born blind?"
Jesus answered, "Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him." The Savior then healed his physical blindness. The Pharisees soon questioned the man trying to force him to deny the miracle and the divinity of the Savior. When he would not, they cast him out.
Then comes my favorite part of the story where Jesus, as He does with all of us, heals the spiritual blindness, "…he said unto him, Dost thou believe on the Son of God?...Who is he, Lord, that I might believe on him? And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee. And he said, Lord, I believe. And he worshipped him." – John 9
