Whether it is cheating in marriage or being unfaithful with your girlfriend or boyfriend, cheating is always a sin. Scripture has a lot to say about infidelity and how it can ruin people. Infidelity can tear entire families apart. It breaks the trust between two people who were once in love and is the ultimate act of betrayal. We must never listen to the whispers of Satan and keep adultery out of our hearts.

The Bible condemns adultery.

There is no way of getting around it. The Bible is very clear that adultery, or cheating on one’s spouse or significant other, is a sin against God. It is our job as Christians to avoid temptation to commit infidelity.

• “Never commit adultery” (Exodus 20:14).
• “Let marriage be kept honorable in every way, and the marriage bed undefiled. For God will judge those who commit sexual sins, especially those who commit adultery” (Hebrews 13:4).
• “Whoever commits adultery with a woman is out of his mind; by doing so he corrupts his own soul” (Proverbs 6:32).

Infidelity will destroy a person.

The Bible says that those who commit adultery will have their reputations ruined and will make themselves a fool. As Christians, we are called to be better. We are instructed to avoid adultery in all forms, so that we can preserve ourselves to be more like Jesus.

• "But the man who commits adultery is an utter fool, for he destroys himself" (Proverbs 6:32).
• "But I say, anyone who even looks at a woman with lust has already committed adultery with her in his heart" (Matthew 5:28).
• "A good name exceeds the value of fine perfume, and the day of someone’s death exceeds the value of the day of his birth" (Ecclesiastes 7:1).

Infidelity goes hand in hand with lying.

When someone commits adultery, they are lying to their significant other about being faithful. Lies can quickly build up trying to hide the transgressions. It is outlined in the Bible that lying is another sin that can quickly take the sinner far away from God.

• "Lying lips are an abomination to the LORD, But those who deal faithfully are His delight" (Proverbs 12:22).
• "Do not lie to one another, for you have stripped off the old nature with its practices and have clothed yourselves with the new nature, which is being renewed in full knowledge, consistent with the image of the one who created it" (Colossians 3:9-10).
• "A righteous person hates deceit, but the wicked person is shameful and disgraceful" (Proverbs 13:5).
• "Truthful words stand the test of time, but lies are soon exposed" (Proverbs 12:19).
• "If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth" (1 John 1:6).

Christians must have integrity.

When someone cheats on their significant other, they lose some of their integrity. Integrity is the quality of having strong moral values and honesty. The Bible says that Christians should walk a life of integrity, and those that do not will go down a path of destruction.

• “People with integrity walk safely, but those who follow crooked paths will slip and fall” (Proverbs 10:9).
• “The one who lives with integrity will be helped, but one who distorts right and wrong will suddenly fall” (Proverbs 28:18).

The truth will always be revealed.

Though a cheater may feel that they are untouchable, God knows the truth. God sees the sins being committed and condemns them, even if the spouse does not know they are being cheated on. The true story will always come to light.

• "There is nothing hidden that won’t be revealed, and there is nothing secret that won’t become known and come to light" (Luke 8:17).
• "Everything that is hidden will be made clear. Every secret thing will be made known" (Mark 4:22).
• "Everyone who practices wickedness hates the light and does not come to the light, so that his actions may not be exposed. But whoever does what is true comes to the light, so that it may become evident that his actions have God’s approval" (John 3:20-21).

Do not seek revenge but offer forgiveness.

Being cheated on is an incredibly painful experience. Wanting to lash out and get revenge is a powerful temptation, but Jesus teaches us to forgive. We do not have to accept the person back into our lives, but we can forgive and let go of the pain. Revenge will only make us feel worse.

• "Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everyone" (Romans 12:17).
• "Make sure that no one ever pays back one wrong with another wrong. Instead, always try to do what is good for each other and everyone else" (1 Thessalonians 5:15).
• "And when ye stand praying, forgive, if ye have ought against any: that your Father also which is in heaven may forgive you your trespasses" (Mark 11:25).

Adultery is a horrible sin, and we must do everything we can to abstain from it. Do not listen to Satan’s whispers of temptation, but rather fill your heart with the love of God. 1 Corinthians 10:13 says “No temptation has overtaken you except what is common to mankind. And God is faithful; He will not let you be tempted beyond what you can bear. But when you are tempted, He will also provide a way out so that you can endure.”
