Have you ever wondered what the Bible really says about adultery? Many people feel confused when they hear this word. Adultery is when someone breaks the promise of marriage and chooses unfaithfulness. It causes pain, breaks trust, and hurts families deeply.
But the good news is this – the Bible does not only warn us about adultery, it also shows us the way of forgiveness, hope, and a new beginning. God’s Word teaches us to stay faithful, to keep our hearts pure, and to find His mercy when we fall.
In this blog, you will find 25 powerful Bible verses about adultery with simple reflections. These verses will guide you, encourage you, and remind you that God’s grace is always greater than our mistakes.
What Does the Bible Say About Adultery?
Adultery means breaking the promise of marriage and being unfaithful to the husband or wife. In the Old Testament, God gave a clear command: “You shall not commit adultery” (Exodus 20:14). In the New Testament, Jesus explained that adultery is not only about action but also about what happens in the heart. If someone looks at another person with lust, it is already sin in God’s eyes (Matthew 5:28).
God takes adultery very seriously because marriage is a holy covenant. It is not only between a husband and wife but also before God. When this promise is broken, it causes pain, destroys love, and moves people away from God’s will.
Why the Bible Warns Against Adultery
The Bible warns us against adultery because it brings many painful results. It breaks trust in marriage, destroys families, and leads people into spiritual darkness. Adultery may look tempting for a short time, but in the end, it brings shame and regret.
Here are some verses that show why God warns us:
- Proverbs 6:32 – “But a man who commits adultery has no sense; whoever does so destroys himself.”
- Job 31:11 – “For that would have been shameful, a sin to be judged.”
- Proverbs 5:22 – “The evil deeds of the wicked ensnare them; the cords of their sins hold them fast.”
God’s Word makes it clear: adultery leads to harm, but faithfulness brings blessing.
