10 Ways to Thwart the Sin of Infidelity

10 Ways to Thwart the Sin of Infidelity

My husband works in an industry dominated by women and required (pre-pandemic) up to half of each month away from home. The time apart leaves us vulnerable to unfaithful opportunities. However, we entered our marriage with a battle plan to protect our marriage. 

Here are 10 ways we take action to thwart the sin of infidelity in our marriage. Note that these are active steps. We, as Christians, live in a world where we cannot wait passively for the attacks on our marriages to come. They are here. They are stealthy. They will destroy. We have to be on the offensive. We have to fight for our marriages. So as you read each of these 10 ways to thwart the sin of infidelity, I encourage you to prayerfully consider how you can adapt them to your battle plan for marriage.

    1. Make marriage a triple-braided cord.

    No marriage should be entered or continued through without God. Growing close to God separately will also draw you together. Pray for each other daily, together if possible, but definitely in the solitude of your quiet time. Ask each other what you can pray for. Just asking allows the opportunity for communication and growth. If you can participate in a Bible study together and discuss what you've learned, all the better!

    "A person standing alone can be attacked and defeated, but two can stand back-to-back and conquer. Three are even better, for a triple-braided cord is not easily broken." (Ecclesiastes 4:12 NLT)

  • <strong>2. Act like you're still dating.</strong>

    2. Act like you're still dating.

    This is something my husband and I do on a modified basis. Managing a date night with caregiving, childcare, and pandemic considerations is near impossible. I'm not one of those advocating to have a date night at least once a week or even once a month. There are other ways to act like you are still dating without making it a special event. Flirt and dress up. Be sneaky and naughty. Drop little random text messages saying that you love your spouse, you prayed for them, or you were thinking about them. Fix a favorite meal, pick up a special item they like without reason, or set aside your to-do-list to relax and do nothing together. I promise the to-do list isn't going away, but choosing your spouse over it speaks volumes of how important they are to you.

    "In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. After all, no one ever hated their own body, but they feed and care for their body, just as Christ does the church— for we are members of his body." (Ephesians 5:28-29)

  • <strong>3. Have lots of sex.</strong>

    3. Have lots of sex.

    God created it, and it was good (inside the context of marriage, of course). In fact, He dedicated a whole book to it. Reread Song of Songs. It makes a lot more sense as a married couple. It is okay to enjoy sex and want it. In fact, Paul tells us not to withhold sex unless for a mutual agreement of fasting and prayer. There is a reason for it. Sex is a foundational part of the marriage relationship. It is where two become one. If you withhold sex or use it as leverage, you've created a door for trouble to slip through.

    "Do not deprive each other of sexual relations, unless you both agree to refrain from sexual intimacy for a limited time so you can give yourselves more completely to prayer. Afterward, you should come together again so that Satan won't be able to tempt you because of your lack of self-control." (1 Corinthians 7:5 NIV)

  • <strong>4. Take your spouse off a pedestal.</strong>

    4. Take your spouse off a pedestal.

    Your spouse is Mr./Mrs. Right, but they aren't Mr./Mrs. Perfect. There will be times when your spouse fails you. They will never be able to fulfill your every need. Only God was meant to do that. Taking your spouse off a pedestal is a personal attitude and spiritual adjustment. Your spouse cannot do it for you, and you cannot do it for them. Check your heart and make sure you haven't elevated your spouse to an idol. Acknowledge to God that only He can fulfill all of your needs, and remind yourself of that fact when hurt and disappointment enter your marriage.

    "And my God will meet all your needs according to the riches of his glory in Christ Jesus." (Philippians 4:19 NIV)

    5. Become an architect.

    Everyone likes to be built up. Build up your spouse, both in private and in public. In private, thank your spouse for the little things and the big things. Recognize even the silliest thing like loading the dishwasher. It seems easy, right? Try that when you are angry or hurt. I try to regularly thank my husband for his hard work and sacrifice for our family. Build your spouse up in public, even when they are not around. While it is easy to vent to others about disappointments, be aware it can get back and become painful. Always build up your spouse to others. Save your venting for your prayer time with God. He can handle it.

    "Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen." (Ephesians 4:29)

  • <strong>6. Count to 10.</strong>

    6. Count to 10.

    Your spouse will do stupid stuff. They will do things that make you angry. They will do something that will make you wonder why you married them. Write down 10 universal character traits about your spouse you love and are thankful for. While your husband may be the sexiest hunk of a man now, that full head of hair may not be there later. Husbands, your wife's body will change. However, character traits don't usually change throughout your life. Maybe you love how your spouse can make you laugh. Write it down and include your favorite memory. Maybe you love how your spouse loves the Lord. Write it down. When you get so upset that all you can see is the bad in your spouse, revisit those 10 things you love about them.

    "Every time I think of you, I give thanks to my God." (Philippians 1:3 NLT)

  • 7. Let it go.

    7. Let it go.

    Once you have forgiven each other of something, truly forgive it. Slam the door on that memory, turn away, and let it go forever. Don't bring up old wounds. Remembering the mistakes of the past doesn't do anything to help the future. Letting it go is difficult, and sometimes those old wounds pop back up, but that is where you take control. You can captivate your thoughts with God's help and forgive that incident as many times as you need. Forgiveness is not saying what they did was okay. Forgiveness is saying I will no longer hold it against you. It is a choice that you will have to make over and over again. 

    "Even if they sin against you seven times in a day and seven times come back to you saying 'I repent,' you must forgive them." (Luke 17:4 NIV)

    8. Have eyes only for your spouse.

    It may sound radical, but don't comment on those other eye-catchers, even if your friends are. Maybe you're more confident than me, but if I heard my husband commenting on other women (even a celebrity), I would feel insecure about my body and how he views me. Don't take a first (let alone a second) look at another person. This will protect you from becoming dissatisfied later. Age, time, and circumstances change bodies. Your spouse needs to know, no matter what, they are the sexiest person in the world to you.

    "But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart." (Matthew 5:28 NIV)

  • <strong>9. Respect your spouse.</strong>

    9. Respect your spouse.

    Love is communicated through respect. Men, especially, thrive on respect or whither without it. Thank your spouse for what they do to help support the family. Take an interest in what gives them satisfaction. Support your spouse in their endeavors, even if you want to roll your eyes. Respect for each other is a protective barrier against infidelity. 

    I always know when my husband is going to have lunch with a coworker. With the way his job is, we can’t have a no one-on-one with the opposite sex rule. However, we do have a rule of no rides alone with the opposite sex, meetings are held in public places with lots of witnesses, and he always lets me know when it is going to happen. His communication with me is a sign of respect for me and our marriage.

    "However, each one of you also must love his wife as he loves himself, and the wife must respect her husband." (Ephesians 5:33 NIV)

  • <strong>10. Uncork the bottle.</strong>

    10. Uncork the bottle.

    No, this is not a reference to drinking. When your spouse does something that bothers you or doesn't do something they said they would do, don't bottle up your frustration. Uncork the bottle and let your spouse know before it becomes a point of bitterness. Communication is key to survival, whether it be over finances or which sports team is better. Don't bottle up your emotions and opinions. Share them honestly and respectfully.

    "Be angry and do not sin. Don't let the sun go down on your anger, and don't give the Devil an opportunity." (Ephesians 4:26-27 HCSB)

    Some of these ideas may seem radical and even silly, but trust me when I say these strategies are what have helped me through 16 years of a roller-coaster life with my husband. Sin is always crouching at the door, waiting for an opportunity to wreck your marriage. Don't be passive and wait for the attack to come. Fight for your marriage. May you thwart the sin of infidelity and have a long, happy marriage that honors and glorifies God.
