Human beings have "free will" in that they are free to will what they wish- but we are not free to DO whatever we wish, because in order to do that you would have to have absolute power over your circumstances, which we don't... unless we are submitting our will to God, who has the power over our circumstances. If we are choosing to submit to God, then it is not only his will that is being done- it's ours too. That's why believers have more free-will than non-believers: because non-believers have freedom of will, but not enough that it can ever be actualized.
Judas was chosen to be a witness for Jesus; but he didn't do that: Betraying Jesus wasn't a decision that God made for Judas; God chose him to be an Apostle; Judas chose to be a traitor. Now, he was chosen to do that which God knew he would choose not to do, because there needed to be someone to betray Jesus; however, that does not mean that Judas did not make the choice.
They were blind because they refused to humble themselves- God offered a chance for them to humble themselves.
PS69
22Let their table become a snare before them,
And their well-being a trap.
23Let their eyes be darkened, that they see not; and make their loins continually to shake.
24Pour out thine indignation upon them, and let thy wrathful anger take hold of them.
25Let their habitation be desolate;
and let none dwell in their tents.
26For they persecute him whom thou hast smitten; and they talk to the grief of those whom thou hast wounded.
27Add iniquity
unto their iniquity: and let them not come into thy righteousness.
28Let them be blotted out of the book of the living, and not be written with the righteous.
29But I
am poor and sorrowful: let thy salvation, O God, set me up on high.
30I will praise the name of God with a song, and will magnify him with thanksgiving.
31This also shall please the LORD better than an ox
or bullock that hath horns and hoofs.
32The humble shall see this, and be glad: and your heart shall live that seek God.
IS29
10For the LORD hath poured out upon you the spirit of deep sleep, and hath closed your eyes: the prophets and your rulers, the seers hath he covered.
11And the vision of all is become unto you as the words of a book that is sealed, which
men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot; for it
is sealed:
12And the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned.
13Wherefore the Lord said, Forasmuch as
this people draw near me with their mouth, and with their lips do honour me,
but have removed their heart far from me, and their fear toward me is taught by the precept of men:
14Therefore, behold, I will proceed to do a marvellous work among this people,
even a marvellous work and a wonder: for the wisdom of their wise
men shall perish, and the understanding of their prudent
men shall be hid.
15Woe unto them that
seek deep to hide their counsel from the LORD, and
their works are in the dark, and they say, Who seeth us? and who knoweth us?
16Surely your turning of things upside down shall be esteemed as the potter's clay: for shall the work say of him that made it, He made me not? or shall the thing framed say of him that framed it, He had no understanding?
17Is it not yet a very little while, and Lebanon shall be turned into a fruitful field, and the fruitful field shall be esteemed as a forest?
18And in that day shall
the deaf hear the words of the book, and the eyes of the blind shall see out of obscurity, and out of darkness.
JOHN9
Jesus said
, “If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains.
Jesus came to open the eyes of the blind. All they had to do was humble themselves and accept Jesus to find favor with God again.
Jesus didn't make Israel reject him. They rejected him despite being chosen to be his people. Yes, God knew they would; but No, it does not mean they didn't choose to stay blind.
Are you sure? I think you have the cause and effect totally backwards.
ROM4
11And he received the sign of circumcision, a seal of the righteousness of the faith which he had yet being uncircumcised:
COL2
6As ye have therefore received Christ Jesus the Lord, so walk ye in him: 7Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving. 8Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. 9For in him dwelleth all the fulness of the Godhead bodily. 10And ye are complete in him, which is the head of all principality and power: 11In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ: 12Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead. 13And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
The "circumcision made without hands" is received from the Spirit of Christ wherein we put off the body of the sins of the flesh and walk in the Spirit. This is not something that preceded faith- it comes as a result of faith.
