Adultery is a Sin.

Adultery is an unrighteous act. In no circumstances can it please God when a person commits adultery. Adultery starts where a person lusts for someone that is not their spouse. God is not pleased when a person covets someone outside of marriage. This is a slippery slope that will lead to adultery. 2nd Peter 2:14 advises us of the sinful and beguiling nature of adultery.

2nd Peter 2:14, “Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children:”

Adultery Comes From Within Our Own Heart.

Adultery is committed by two willing partners. One person in the relationship may have been the temptress or tempter, but the other person accepted the temptation. When we have lust in our eyes for a person who is married to another, God considers us adulterers. Matthew 5:28 advises us that adultery starts in our hearts.

Matthew 5:28, “But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.”

Adultery is a Work of the Flesh.

Most societies do not consider adultery a crime. Things like littering and illegal parking are a crime, but not adultery. On the other hand, the Bible categorizes adultery with murder, heresies, and other works of the flesh. Galatians 5:19 defines adultery as a work of the flesh.

Galatians 5:19, “Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,”
