Those who think they are righteous?

I came not to call the righteous, but sinners to repentance. Jesus in Luke 5:32

Jesus came not to call the righteous...Hmm. Since Romans says that there is none righteous no not one then there are no righteous persons. So in effect all are sinners and all need salvation but then why would Jesus say, "Not to call the righteous?" I was taken back by the translators or paraphrase of the New Living version of the Bible. They translate that Jesus did not come to call..."Those that think they are righteous." Hmm, well Jesus was talking to the Pharisees and they did think they were righteous. They were accusing Jesus of hanging out with sinners which he was. So I am thinking -- is the gospel message centrific only to those who perceive themselves as sinful. Can it be that those who believe they are righteous and don't need a redeemer are inoculated from the healing power to the problem of sin?
