1 Thessalonians 4:3-7

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.

6No man among you should ever have sex with the wife of a Christian friend. That would be the same as if you robbed him. It would be a bad thing to do against him. Remember that the Lord will punish everyone who does things like that. We have already told you that. We warned you very seriously about it.

7God has chosen us to belong to him. He does not want us to do disgusting things. As his people, he wants us to be holy.
