1 Thessalonians 4:4-7

Yes, each of you must guard your sexual purity with holiness and dignity, not yielding to lustful passions like those who don’t know God. Never take selfish advantage of a brother or sister in this matter, for we’ve already told you and solemnly warned you that the Lord is the avenger in all these things. For God’s call on our lives is not to a life of compromise and perversion but to a life surrounded in holiness.
