You need to read more carefully. I never said that Jesus said they were righteous. I said they believed they had no need of repentance as they did not view themselves as sinners.
The parable MOCKED them by showing that heaven rejoiceth over those who know they are sinners and repented rather than over those who saw themselves as never lost and never needing repentance. Jesus merely pictured them as they perceived themselves while picturing the publican's and sinners as they perceived themselves - sinners in need of repentance.
No, Jesus was not mocking the Pharisees. Jesus was showing the Pharisees that these "sinners" they despised were God's sheep and that God valued them very highly. If even one was lost, God would go out like a shepherd and seek that lost sheep. So much for Limited Atonement.
Now, it was Jesus himself who spoke of 99 sheep that did not go astray and needed no repentance.
Luk 15:7 I say unto you, that likewise joy shall be in heaven over one sinner that repenteth,
more than over ninety and nine just persons, which need no repentance.
These 99 just persons which need no repentance do not match up with the Pharisees. First of all, there were not 99 Pharisees for every sinner in Israel. Second, Jesus never gave the Pharisees the impression they were just and needed no repentance.
Although parables are fiction, they still reflect genuine spiritual truths. I simply do not believe Jesus would speak of fictional persons that could not possibly exist if Original Sin is true.
No, I believe the 99 just persons represent children who have not sinned yet. This is supported in Matthew 18 where Jesus repeats this same parable speaking of little children.
Mat 18:12 How think ye? if a man have an hundred sheep, and one of them be gone astray, doth he not leave the ninety and nine, and goeth into the mountains, and seeketh that which is gone astray?
13 And if so be that he find it, verily I say unto you, he rejoiceth more of that sheep,
than of the ninety and nine which went not astray.
14 Even so it is not the will of your Father which is in heaven, that one of
these little ones should perish.
Matthew 18 is all about little children. Jesus places a small child in the midst of his disciples and tells them they must be converted and become as little children to enter heaven. Jesus said that these little children have angels who always behold his Father's face.
This is hardly describing horrible little sinners.
Then once again, Jesus repeats the parable of a shepherd with 100 sheep (none are lost). One goes astray and becomes lost, the shepherd searches until he recovers it. Then he repeats there is more joy over this lost sheep who is recovered than 99 sheep which WENT NOT ASTRAY.
Then Jesus clearly says it is not his Father's will that one of THESE LITTLE ONES should perish.
So, I believe there is strong scriptural evidence to show Jesus is speaking of little children when he speaks of the 99 just persons who never went astray and need no repentance.
