'Impure' in the Bible

“Woe to you, [self-righteous] scribes and Pharisees, hypocrites! For you are like whitewashed tombs which look beautiful on the outside, but inside are full of dead men’s bones and everything unclean.

I wrote you in my [previous] letter not to associate with [sexually] immoral people—

Do you not know that the unrighteous will not inherit or have any share in the kingdom of God? Do not be deceived; neither the sexually immoral, nor idolaters, nor adulterers, nor effeminate [by perversion], nor those who participate in homosexuality,

For our appeal does not come from delusion or impure motives, nor [is it motivated] by deceit [our message is complete, accurate, and based on the truth—it does not change].

for sexually immoral persons, for homosexuals, for kidnappers and slave traders, for liars, for perjurers—and for whatever else is contrary to sound doctrine,

But have nothing to do with irreverent folklore and silly myths. On the other hand, discipline yourself for the purpose of godliness [keeping yourself spiritually fit].

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.”
