'Impure' in the Bible

There will no longer exist anything that is cursed [because sin and illness and death are gone]; and the throne of God and of the Lamb will be in it, and His bond-servants will serve and worship Him [with great awe and joy and loving devotion];

Let the one who does wrong, still do wrong; and the one who is filthy (vile, impure), still be filthy; and the one who is righteous (just, upright), still be righteous; and the one who is holy, still be holy.”
