1 Thessalonians 4:3-5

3This is how God wants you to live: As his own people, he wants you to be completely good. So you must not have sex in a way that is wrong.

4Each of you men must learn to rule his own body properly. Then you will do only what is pure and right.

5People who do not know God strongly want to have sex in a wrong way. They cannot control themselves. You must not be like those people.
