Marriage is a sacred institution created by God. It is a union designed to bring two people together in love, commitment, and trust. However, one of the most damaging betrayals in a marriage is infidelity or cheating. In the Bible, God speaks clearly about the importance of faithfulness, purity, and the sacredness of the marital bond. Throughout the Scriptures, adultery is considered a serious sin and a breach of the trust that is foundational to marriage.
In this article, we will explore 30 Bible verses about cheating in marriage, helping us understand God’s perspective on infidelity and the importance of maintaining a faithful, loving relationship with our spouses.
The Importance of Faithfulness in Marriage
Faithfulness in marriage is not only a moral obligation but also a spiritual one. God calls His people to be faithful in their relationships, and this includes faithfulness in marriage. Adultery disrupts the sacred bond between husband and wife, and it violates God’s commandments.
The Bible is full of verses that emphasize the sanctity of marriage and the danger of infidelity. Let’s look at some of these verses that highlight God’s stance on cheating in marriage.
1. Exodus 20:14 – The Seventh Commandment
“You shall not commit adultery.” (Exodus 20:14, ESV)
The seventh commandment is clear: adultery is a sin. God’s Word makes it plain that marital faithfulness is essential. Cheating is a violation of this commandment, which sets a standard for all believers to follow.
2. Leviticus 20:10 – Adultery is a Serious Offense
“If a man commits adultery with the wife of his neighbor, both the adulterer and the adulteress shall surely be put to death.” (Leviticus 20:10, ESV)
In the Old Testament, adultery was considered a serious offense. Although the specific punishments in the Old Testament may not apply today, the severity of the sin remains the same. Adultery destroys trust and harms the marriage covenant.
3. Proverbs 6:32 – Adultery Destroys
“He who commits adultery lacks sense; he who does it destroys himself.” (Proverbs 6:32, ESV)
Adultery not only destroys relationships but also harms the individual committing the act. It leads to regret, brokenness, and long-lasting consequences. God warns us that infidelity damages both our relationships and our souls.
4. Matthew 5:27-28 – Lust and Adultery in the Heart
“You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.” (Matthew 5:27-28, ESV)
Jesus takes adultery a step further by addressing the issue of lust. He teaches that even lusting after someone in your heart is sinful and equates it to adultery. This shows that faithfulness begins in the heart and mind, not just with actions.
5. Matthew 19:6 – The Sanctity of Marriage
“So they are no longer two but one flesh. What therefore God has joined together, let not man separate.” (Matthew 19:6, ESV)
Marriage is a union that God establishes, and it is meant to be permanent. Cheating in marriage violates this sacred bond. Jesus affirms that marriage is intended to be a lifelong commitment between husband and wife.
6. Mark 10:11-12 – Adultery and Divorce
“And he said to them, ‘Whoever divorces his wife and marries another commits adultery against her; and if she divorces her husband and marries another, she commits adultery.’” (Mark 10:11-12, ESV)
Jesus emphasizes the sanctity of marriage and warns that divorce and remarriage outside the original marriage are acts of adultery. Cheating in marriage is a sin that can lead to brokenness and the possibility of divorce, but God’s design is for marriage to be permanent.
7. Romans 13:9 – Fulfillment of the Law
“The commandments, ‘You shall not commit adultery, you shall not murder, you shall not steal, you shall not covet,’ and any other commandment, are summed up in this word: ‘You shall love your neighbor as yourself.’” (Romans 13:9, ESV)
Paul points out that all the commandments, including the prohibition against adultery, are rooted in love. If we truly love our spouses and others, we will remain faithful to them, as adultery is a violation of that love.
8. 1 Corinthians 6:9-10 – The Unrighteous Will Not Inherit the Kingdom
“Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God.” (1 Corinthians 6:9-10, ESV)
Adultery is listed among the behaviors that prevent people from inheriting the kingdom of God. This highlights the seriousness of infidelity and the need for repentance and restoration.
9. 1 Corinthians 7:2 – The Marital Duty
“But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband.” (1 Corinthians 7:2, ESV)
Paul underscores the importance of sexual faithfulness within marriage. Marriage provides a safe space for sexual expression, and infidelity breaks that trust and the covenant between husband and wife.
10. Hebrews 13:4 – Honor Marriage
“Let marriage be held in honor among all, and let the marriage bed be undefiled; for God will judge the sexually immoral and adulterous.” (Hebrews 13:4, ESV)
God’s design for marriage is to be honored and respected. Infidelity, which defiles the marriage bed, is condemned by God. Faithfulness is key to preserving the sanctity of marriage.
11. Revelation 21:8 – The Unrepentant Will Face Judgment
“But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.” (Revelation 21:8, ESV)
The sexually immoral, including adulterers, face severe judgment unless they repent. The Bible warns that unrepentant sin, including infidelity, will have eternal consequences.
12. Proverbs 5:3-4 – The Dangers of Adultery
“For the lips of a forbidden woman drip honey, and her speech is smoother than oil, but in the end she is bitter as wormwood, sharp as a two-edged sword.” (Proverbs 5:3-4, ESV)
Adultery may seem tempting, but the consequences are painful. Proverbs warns about the deceptive allure of infidelity, which ultimately leads to bitterness and destruction.
13. Proverbs 6:27-29 – Consequences of Adultery
“Can a man carry fire next to his chest and his clothes not be burned? Or can one walk on hot coals and his feet not be scorched? So is he who goes in to his neighbor’s wife; none who touches her will go unpunished.” (Proverbs 6:27-29, ESV)
Adultery, like carrying fire, leads to inevitable consequences. The Bible warns that those who engage in infidelity will not escape the damage it causes.
14. James 1:14-15 – Temptation and Sin
“But each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death.” (James 1:14-15, ESV)
Cheating often begins with unchecked desires. James explains that sin starts with temptation, but when acted upon, it leads to death—spiritual, emotional, and sometimes even physical.
15. Proverbs 7:25-27 – The Path to Destruction
“Let not your heart turn aside to her ways; do not stray into her paths, for many a victim has she laid low, and all her slain are a mighty throng. Her house is the way to Sheol, going down to the chambers of death.” (Proverbs 7:25-27, ESV)
Adultery is portrayed as a path that leads to destruction. The Bible cautions us to avoid it, as it ultimately leads to spiritual and relational ruin.
16. Malachi 2:14-16 – God Hates Divorce
“For the man who does not love his wife but divorces her, says the Lord, the God of Israel, covers his garment with violence, says the Lord of hosts. So guard yourselves in your spirit, and do not be faithless.” (Malachi 2:16, ESV)
God detests faithlessness in marriage, including infidelity that leads to divorce. He calls His people to remain faithful, honoring the vows they made before Him.
17. Ephesians 5:25-33 – Love in Marriage
“Husbands, love your wives, as Christ loved the church and gave himself up for her… However, let each one of you love his wife as himself, and let the wife see that she respects her husband.” (Ephesians 5:25, 33, ESV)
The love between husband and wife should reflect the sacrificial love of Christ for the church. Cheating in marriage goes against this selfless love and respect.
18. 1 Thessalonians 4:3-5 – Living in Holiness
“For this is the will of God, your sanctification: that you abstain from sexual immorality; that each one of you know how to control his own body in holiness and honor.” (1 Thessalonians 4:3-4, ESV)
God’s will is for His people to live in holiness, and that includes sexual purity. Infidelity is a violation of this call to live a life of sanctification and honor.
19. Colossians 3:5 – Put to Death Sexual Sin
“Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry.” (Colossians 3:5, ESV)
Paul instructs believers to put away all forms of sexual sin, including adultery. Sexual sin is not to be part of the believer’s life but should be actively fought against.
20. 1 Timothy 3:2 – The Qualifications for Leaders
“Therefore an overseer must be above reproach, the husband of one wife, sober-minded, self-controlled, respectable, hospitable, able to teach.” (1 Timothy 3:2, ESV)
Leaders in the church are called to be above reproach, including in their marriages. A leader who is unfaithful to his spouse is not fit for leadership in the body of Christ.
Conclusion
The Bible speaks powerfully about cheating in marriage, making it clear that adultery is a serious sin that dishonors God, hurts individuals, and damages relationships. However, the Bible also offers hope for forgiveness and healing. For those who have fallen into sin, there is a call to repentance, and God’s grace is available to restore broken relationships.
God desires that marriages be faithful and that husbands and wives love and honor each other in ways that reflect His love for His people. If you are struggling with issues of infidelity, turn to God for strength, and seek reconciliation through His grace.
