The problem as I see it, is the way the various translations deal with the Greek preposition εἰς in John 9:39. Here's how I would translate the verse:
I have chosen "with judgment" as the best way of translating "Εἰς κρίμα" instead of "for judgment" as many of the translations have done. I do this because "judgment" was not the purpose of Jesus coming into the world, but was a consequence, i.e. judgment followed him into the world.
Jesus Declares His Purpose
The writer of the Gospel of Luke informs us that after being tempted in the wilderness Jesus returned to Galilee, and read to his own people these words from the prophet Isaiah:
18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, 19 To preach the acceptable year of the Lord.
-- Luke 4:18-19 (KJV)
When he returned to his seat after reading from the scroll every eye in the synagogue was fixed on him, and he said:
... This day is this Scripture fulfilled in your ears.
-- Luke 4:21 (KJV)
There was no sense of judgment in the words that Jesus read from the scroll, and the people "wondered at the gracious words which proceeded out of his mouth" (Luke 4:22).
And Judgment Followed Him
Sensing the inclination of their hearts, Jesus challenged the congregation in regard to obligation, i.e. paraphrasing Luke 4:23, "You will expect me to do for you what you have been told I did in Capernaum, but I won't be able to, because to you I am just Joseph's son".
Jesus then drew the attention of the congregation to Elijah and Elisha as prophets who were sent to particular "foreigners" to do a special work, whereupon the congregation flew into a rage, wanting to throw Jesus out of their city (Luke 4:28-29).
The people of the synagogue had the WORDS of God in their midst. Generation after generation they would have brought them out on the Sabbath, reading them and discussing their implications, but their blindness to the One the words testified of was only made manifest when the WORD of God, Jesus himself, stood in their midst and suggested that familiarity would prevent him from being able to do any great work amongst them. Indeed, this revelation made them angry enough to want to "lead him unto the brow of the hill whereon their city was built, that they might cast him down headlong."
The people of Jesus' home region JUDGED him worthy of death, and in doing so CONDEMNED themselves to a state of ongoing suffering without the benefit of what he could have done for them.
Herein is the judgment of God delivered WITH Jesus: the same WORDS of God can be preached to both rich and poor in spirit, but the WORD of God will become a blessing to those who think they are poor (taking advantage of what Jesus has to offer), and an offense to those who think they are rich (judging that they already possess in good measure anything Jesus has to offer, and it is offensive for him to insinuate otherwise).
Jesus didn't come for the purpose of JUDGMENT, he came rather for the purpose of HEALING the brokenhearted, to INFORM them that deliverance from captivity was a reality, that seeing God was a reality, and that freedom from oppression was a reality. In the wake of this work, judgment inevitably followed as Jesus' words indicted those whose hearts were filled with a sense of their own righteousness.
The writer of the letter to the Hebrews said this:
For the word λόγος of God is quick, and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
-- Hebrews 4:12 (KJV)
And the Logos says this (emphasis mine):
34 O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. 35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things. 36 But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. 37 For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
-- Matthew 12:34-37 (KJV)
