Charles Spurgeon Commentary John 8:34-38

"Jesus answered them, Verily, verily, I say unto you, Every one that committeth sin is the bondservant of sin. And the bondservant abideth not in the house for ever: the son abideth for ever. If therefore the Son shall make you free, ye shall be free indeed. I know that ye are Abraham`s seed: yet ye seek to kill me, because my word hath not free course in you. I speak the things which I have seen with [my] Father: and ye also do the things which ye heard from [your] father." — John 8:34-38 (ASV)

And they cast him out. Jesus heard that they had cast him out; and when he had found him, he said to him, Do you believe on the Son of God? He answered and said, Who is he, Lord, that I might believe on him? And Jesus said to him, You have both seen him, and it is he that talks with you. And he said, Lord, I believe. And he worshipped him.

Then his cure was indeed complete. He had seen Christ spiritually as well as naturally, and fell at his feet, and worshipped him as the Son of God.
