Colossians 3:5

Your old nature likes to do bad things that belong to this earth. But your old nature is dead, so do not do these bad things any more. Do not have sex with someone that you are not married to. Do not think bad, disgusting thoughts. Do not want to have sex in a wrong way. Do not want to do any kinds of bad things. Do not want to have many things for yourselves. That shows that you worship those things as your idol.
