I'd be careful:

1Jo 1:8 If we say we have no sin, we deceive ourselves, and the truth is not in us.
1Jo 1:9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
1Jo 1:10 If we say we have not sinned, we make him a liar, and his word is not in us.

We all sin-Christians included. It's just that God the Father uses us in spite of our nature. And He can look on us because of the precious work of Christ.

Peter warned Christians not to be considered a "a murderer or a thief or an evildoer or as a meddler" (I Pet 4:15). And Paul tells us not to think more highly of ourselves as we should.
