When the disciples saw a man who had been blind from birth, they asked Jesus what kind of sin had caused this blindness. The Jews had understood that many infirmities were the result of human folly and sin. Jesus answered that God had allowed this infirmity for a greater purpose which God wanted to demonstrate as a sign of his presence and power. Jesus then made a claim which only God could rightfully make. Jesus stated unequivocally, I am the light of the world (John 9:5). In so many words Jesus was saying that he is the one true source of power and light which sustains life and overcomes the darkness of sin, confusion, and spiritual blindness. Jesus’ mighty works – his miraculous signs – confirmed the truth of his message and claim to divine authority and equality with his Father in heaven. The Lord Jesus is ever ready to heal us and to free us from the darkness of sin and deception. Isaiah prophesied that the “Suffering Servant” would be bruised for our iniquities and by his stripes we would be healed (Isaiah 53:5). Augustine of Hippo, in his commentary on this gospel passage, remarks: “If we reflect on the meaning of this miracle, we will see that the blind man is the human race …You already know, of course, who the “One Sent” is. Unless he had been sent, none of us would have been freed from sin.”
