But if they lack self-control, let them marry. It is better to marry than to burn.

1 Coríntios 7:9

Do not be yoked up, like unmatched animals, with unbelievers. For what partnership have righteousness and lawlessness, or what fellowship has light with darkness,

or what harmony has Christ with Belial, or what share has a believer with an unbeliever?

2 Coríntios 6:14,15

18 Shun unchastity. Every other sin that a man does is apart from the body, but the unchaste sins against his own body.

19 Do you not know that your body is the temple of the Holy Spirit within you, which you have from God, and that you are not your own?

20 For you were bought with a price. Glorify God then in your bodies.

1 Coríntios 6:18-20

Food of all kinds is for the stomach and the stomach for foods. But God will end the function of one and the other. The body is not for unchastity, but for the Lord, and the Lord is for the body.

1 Coríntios 6:13

Do not be led astray; "bad associations corrupt good morals."

1 Coríntios 15:33

Let marriage be held in honor by all and let the bed be undefiled; for unchaste persons and adulterers God will judge.

Hebreus 13:4

Above all these, clothe yourselves with love, which is the perfect bond of union.

Colossenses 3:14
