1 Thessalonians 4:6-8

6This means one must not transgress against and take advantage of a brother or sister in this manner, because the Lord is an avenger of all these offenses, as we also previously told and warned you.

7For God has not called us to impurity but to live in holiness.

8Consequently, anyone who rejects this does not reject man, but God, who gives you his Holy Spirit.
