Jesus Christ is God. He gives sight to the spiritually blind so they can see the truth.
'Now we know that God heareth not sinners: but if any man be a worshipper of God, and doeth his will, him he heareth.
Since the world began was it not heard that any man opened the eyes of one that was born blind.
If this man were not of God, he could do nothing.
They answered and said unto him, Thou wast altogether born in sins, and dost thou teach us? And they cast him out.
Jesus heard that they had cast him out; and when he had found him, he said unto him, Dost thou believe on the Son of God?
He answered and said, 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.
And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind.
And some of the Pharisees which were with him heard these words, and said unto him, Are we blind also?
Jesus said unto them, If ye were blind, ye should have no sin: but now ye say, We see; therefore your sin remaineth.'
'For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.'I Cor 13:12
