But the Pharisees and the teachers of the law who belonged to their sect complained to his disciples, "Why do you eat and drink with tax collectors and sinners?" Jesus answered them, "It is not the healthy who need a doctor, but the sick. I have not come to call the righteous, but the sinners to repentance."
Luke 5: 30-31
Jesus is the ultimate champion for the underdog! He doesn't want us to surround ourselves with the righteous (really the self-righteous, because we all have sin). He wants us to court the sinners and bring them to Him. He wants us, in all of our wickedness, to accept the Holy Spirit into our hearts. So do not turn your back on the addicts, the thieves, the adulterers. Welcome them, love them, bring them to Jesus. We cannot overcome sin without Christ, and they can't either.
