“Sinner” is a present-tense description of everyone, including those who have put their faith in Christ. Of course, those who have called Jesus “Lord” are justified, meaning that they are no longer guilty. Also, they have been given the Spirit, which makes them slaves to Christ rather than to sin. But we all are sinners. Perfection awaits eternity.
