John 9

Then the Pharisees also asked him again how he had received his sight. He said to them, “He put clay on my eyes, and I washed, and I see.”..And Jesus said, “For judgment I have come into this world, that those who do not see may see, and that those who see may be made blind.” vv.15,39

Read chapter 9
This is the first time ever of this miracle of the blind seeing!  (At least never recorded of in scripture of being born blind and healed.)  Surely this blind man had no hope of ever seeing, so when the miracle was performed he couldn't deny this was someone sent from God.  Genesis 2:7 says we're made of dust, how fitting is it that Jesus uses dust to open the blind man's eyes.  Truly the Creator using creation that made the first man was standing before this blind man.
The sad truth of blindness of sight verses blindness of the heart is what the point seems to be of this chapter.  The blind man knew he was blind and needed help, yet the Pharisees did not know the blindness of their hearts to see the truth that was right in front of them and not wanting to be healed to see the truth.  
What areas of your heart might you be blind to?  Ask the Lord that you may see!
