What does the Bible say about adultery?

Adultery, the act of marital infidelity, is a topic of significant moral and ethical importance in many cultures and religions, including Christianity. The Bible addresses adultery in both the Old and New Testaments, offering guidance and wisdom on this sensitive issue.

Adultery is a major violation of the sanctity of marriage, and it is penalized in the Bible as a sin against God and against one’s spouse. Adultery is defined as a sexual relationship between a married person and someone who is not their spouse. There are many challenges to staying faithful in a marriage, including financial struggles, challenging children, and immaturity. However, there are ways to overcome these hardships. For example, couples should avoid trying to change each other and keep divorce off the table. They should also seek supportive people who will fight for their marriage and lean on each other during difficult times. The Bible provides guidance on how to avoid adultery. It also speaks of the consequences of this sin. This article will explore what the Bible says about adultery and what we can learn from it.
