Illustration on Adultery: The Aftermath of Adultery ...

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.

See Scripture Commentary: 2 Peter 2:14 advises us of the sinful and beguiling nature of adultery.

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.

See Scripture Commentary: Matthew 5:28 advises us that adultery starts in our hearts.

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.

See Scripture Commentary: Galatians 5:19 defines adultery as a work of the flesh.
