Titus 1:14-15

14They must not listen to Jewish stories that are not true, or to human rules. Those things are the ideas of people who refuse to obey God's true message.

15If someone is clean and good inside, everything is clean and good for them to enjoy. But if someone is not a believer and has an unclean mind, nothing is clean or good for that person. Their minds no longer think properly. They no longer feel guilty when they do something wrong.
