4) Sometime later Jesus heard of the Pharisees' reaction to His healing of the blind man and said to some of them, "If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains." (NIV) What did Jesus mean by that remark?
Blindness is not caused by one's sin.
The Pharisees were guilty of sin because they did not allow blind persons into the synagogue.
The Pharisees were guilty of sin because they had heard the truth Jesus spoke, but did not believe.
Those who are "blind" to their own sin will never enter the kingdom of God.
