Adultery includes the following:
- The sinful sexual lust of the heart.
Matt. 15:19: Out of the heart proceed evil thoughts, murders, adulteries, fornications.
Col. 3:5-6: Mortify, therefore your members which are upon the earth: fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness which is idolatry, for which things’ sake the wrath of God cometh on the children of disobedience. - Covetous or seductive looks and gestures:
Matt. 5:27-28: Jesus said: Ye have heard that it was said by them of old time, thou shalt not commit adultery. But I say unto you, that whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
2 Pet. 2:14. Having eyes full of adultery, and that cannot cease from sin... cursed children. - Improper talk and double-entendres:
Eph. 5:3-4: But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints. Neither filthiness, nor foolish talking, nor jesting, which are not convenient; but rather giving of thanks.
- All other forms of sexual immorality such as sexual relationships outside of marriage, adultery, group sex, rape, seduction, homosexuality, bestiality, etc.
Heb. 13:4: Marriage is honorable in all, and the bed undefiled, but whoremongers and adulterers God will judge.
Note: The word ´marriage´, as it is used here, is the translation of the Greek word ´gamos´, which means nuptials or the marriage feast. God therefore wants Christians to honor the marriage ceremony.1 Cor. 5:1: It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father’s wife.
Rom. 1:26-27: For this cause God gave them up unto vile affections: for their women did change the natural use into that which is against nature. And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
Lev. 18:23: Neither shalt thou lie with any beast.
