John 9:39 - Sin, pride and blindness

John 9:39 "Jesus then said: "For this judgement I came into this world, that those not seeing might see and those seeing might become blind." Those of the Pharisees who were with him heard these things, and they said to him: "We are not blind also, are we?" Jesus said to them: "If you were blind, you would have no sin. But now you say,  "We see." Your sin remains."

This verse is really interesting and took me a moment to sit with and understand.  I think it relates to pride.  He's talking with the Pharisees and they were known to be prideful in their understandings and beliefs and this is something that kept them from believing in Jesus.  It seems that Jesus is saying that if the Pharisees had the humility and felt the suffering of blindness, they would have less pride and be more like a child of God and therefore, no sin.  But because they said "we see", its almost as if they are saying "we know", as if their previous understandings and beliefs passed down to them and rules prevent them from seeing Jesus and that he is send from God, so their sin remains, and they are, ironically because of this spiritually blind.
