Isa 35:4-6,Mt 11:4-5, Jn 9:2-7, 20-22, 35-39
The Old Testament says that the blind cannot come to God. (Lev 21:17-18)
Lev 21:17 Speak unto Aaron, saying, Whosoever he be of thy seed in their generations that hath any blemish, let him not approach to offer the bread of his God. 18 For whatsoever man he be that hath a blemish, he shall not approach: a blind man, or a lame, or he that hath a flat nose, or any thing superfluous,
In the Old Testament, it was foretold that Christ would come and open the eyes of the blind. (Isa 35:4-6)
Isa 35:4 Say to them that are of a fearful heart, Be strong, fear not: behold, your God will come with vengeance, even God with a recompence; he will come and save you. 5 Then the eyes of the blind shall be opened, and the ears of the deaf shall be unstopped. 6 Then shall the lame man leap as an hart, and the tongue of the dumb sing: for in the wilderness shall waters break out, and streams in the desert.
Jesus opened the eyes of the blind and revealed that he was the Christ prophesied in the Old Testament. (Matthew 11:4-5, John 9:2-7, 20-21, 35-39)
Matthew 11:4 Jesus answered and said unto them, Go and shew John again those things which ye do hear and see: 5 The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the gospel preached to them.
John 9:2 And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind? 3 Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him. 4 I must work the works of him that sent me, while it is day: the night cometh, when no man can work. 5 As long as I am in the world, I am the light of the world. 6 When he had thus spoken, he spat on the ground, and made clay of the spittle, and he anointed the eyes of the blind man with the clay, 7 And said unto him, Go, wash in the pool of Siloam, (which is by interpretation, Sent.) He went his way therefore, and washed, and came seeing. 20 His parents answered them and said, We know that this is our son, and that he was born blind: 21 But by what means he now seeth, we know not; or who hath opened his eyes, we know not: he is of age; ask him: he shall speak for himself. 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? 36 He answered and said, Who is he, Lord, that I might believe on him? 37 And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee. 38 And he said, Lord, I believe. And he worshipped him. 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.
