Also why does Jesus say that "they which see might be made blind"?
John 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.
They that see not know they are blind, and are confessing the truth about themselves.
Knowing that they need a doctor, and hearing of Jesus of Nazareth, they gladly hear and receive the words of Jesus, trust to his car, and because he is the only begotten Son of God, they are healed by him, and now they can see.
God has judged to let it be that, “they that see might be made blind” because, they might deny they are blind.
Therefore, “they that see, might be made blind” if they refuse to confess the truth.
God, knows that all men know they are blind. (Consider that man seeks to alleviate his sciences by pursing science)
But, what if you are blind?
How would you know?
You’d know you are blind because you stumble around like a blind man.
But the blind leaders could rely on the best technology science can provide and claim to see better, and further than the average joe, and; with some lying, and a convenient set of assumptions, they could endeavor to lead blind people into delusion.
John 9:40 And some of the Pharisees which were with him heard these words, and said unto him, Are we blind also?
John 9:41 Jesus said unto them, If ye were blind, ye should have no sin: but now ye say, We see; therefore your sin remains.
Another proof of blindness is the inability of intelligent people to understand the sayings of Jesus. (A swish over the head of the Pharisees kind of thing, if you know what I mean)
For if they deny they are blind they desire to remain blind, and in fairness, God gives them over to their blindness.
But, remember, they will continue to deny it, irregardless of evidences to the contrary.
The reason folks don’t understand Jesus is simply because although some men say they believe him they in truth don’t.
That is, to be blunt, an atheist is blind, and may chose to remain blind.
