'Sexual Immorality' in the Bible

Foods are intended for the stomach, and the stomach for foods, but God will finally put a stop to both of them. The body is not intended for sexual immorality but for the service of the Lord, and the Lord is for the body to serve.

Keep on running from sexual immorality! Any other sin that a man commits is one outside his body, but the man who commits the sexual sin is sinning against his own body.

but because of so much sexual immorality every man should have a wife of his own, and every woman a husband of her own.
