This is the sixth miracle recorded in John. Each miracle has been chosen with a view to the spiritual lessons they can teach. There are seven miracles in this gospel.
The Changing of the Water into Wine
The Healing of the Nobleman’s Son
The Curing of the Impotent Man at the pool of Bethesda
The Feeding of the Five Thousand
Christ Walking on the Water
The Restoring of Sight to the Man Born Blind
The Raising of Lazarus
These miracles were chosen in order that those who read about them might be led to faith in Jesus Christ as the Messiah and the Son of God. http://ref.ly/Jn20.31
The neighbors argued over whether he was the same man who used to sit and beg. If so, it was incredible that he could see. Perhaps, they said, it was a case of mistaken identity, but he insisted he was the same man.
If he was the same man, how could he have received his sight? They knew that he was born blind. He made a factual statement concerning his healing. He said a man called Jesus made mud or clay with spit, and then anointed his eyes. This is one of two incidents where Jesus uses spit. The other incident is when He spit on His finger and touched the tongue of the deaf and mute man. Mark 7:33. The use of spit was common in those days. The spit of distinguished individuals was believed to have curative or medicinal properties. After Jesus did that, the man was told to go wash in the Pool of Siloam. This word means “sent.”
When the man returned, he came seeing.
I have decided to include more information on this miracle in Note 5: The Interrogation of the Blind Man. This is research done from Andrew Lincoln’s book entitled “Truth on Trial.”
