Titus 1:15-16
Titus 1:15-16 NCV
To those who are pure, all things are pure, but to those who are full of sin and do not believe, nothing is pure. Both their minds and their consciences have been ruined. They say they know God, but their actions show they do not accept him. They are hateful people, they refuse to obey, and they are useless for doing anything good.
