Joh 9:2 And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind?
Joh 9:3 Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him.
Joh 9:16 Therefore said some of the Pharisees, This man is not of God, because he keepeth not the sabbath day. Others said, How can a man that is a sinner do such miracles? And there was a division among them.
Joh 9:24 Then again called they the man that was blind, and said unto him, Give God the praise: we know that this man is a sinner.
Joh 9:25 He answered and said, Whether he be a sinner or no, I know not: one thing I know, that, whereas I was blind, now I see.
Joh 9:31 Now we know that God heareth not sinners: but if any man be a worshipper of God, and doeth his will, him he heareth.
Joh 9:32 Since the world began was it not heard that any man opened the eyes of one that was born blind.
Joh 9:34 They answered and said unto him, Thou wast altogether born in sins, and dost thou teach us? And they cast him out.
Joh 9:41 Jesus said unto them, If ye were blind, ye should have no sin: but now ye say, We see; therefore your sin jremaineth.
Jesus makes the point that it is only through him that one can see beyond the darkness to the light.
Joh 9:35 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?
Joh 9:36 He answered and said, Who is he, Lord, that I might believe on him?
Joh 9:37 And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee.
Joh 9:38 And he said, Lord, I believe. And he worshipped him.
Joh 9:39 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.
Note in this chapter and the previous one Jesus speaks clearly about the light.
Joh 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
Joh 9:5 As long as I am in the world, I am the light of the world.
Rev 3:18 I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see.
Mat 13:15 For this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
Mat 13:16 But blessed are your eyes, for they see: and your ears, for they hear.
Mar 8:18 Having eyes, see ye not? and having ears, hearye not? and do ye not remember?
