EXCELLENT question!
Seems to me most of the most outspoken Christians I have met spend most of their time proclaiming how righteous and beloved of God they are.
Some churches and churchmembers are so righteous they won't even allow sinners to attend services. Or at least sinners not related to anyone in the church hierarchy.
If you really have encountered, and they are out there, the kind of "Christians?" that think they don't sin anymore you have my pity. But they are a pretty small minority. Jesus encountered folks like that and he had no kind words for them.
The rest will tell you what John wrote "If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us." I John 1:8-10
Paul confessed it on an even more personal level in Romans 7 "For the good that I would I do not: but the evil which I would not, that I do."
Just cause they don't believe they have sinners in their church doesn't change what the book says, in fact it just proves it.
