Mortify therefore your members which are upon the earth  .  .  . uncleanness.
Many of the jokes on a lot of the TV shows and movies and those made by stand-up comedians have a sexual undertone. The language of many, especially teenagers, is filthy. As a Christian, I need to put to death (that’s what “mortify” means) my unclean thoughts, words and actions, and show by my speech and behavior that I really do belong to the Lord Jesus Christ. Let’s be clean Christians.
