If you only watched popular media, you might assume that Christian couples are uncomfortable talking about sex. You could even come away believing that wanting to improve your marital sex life is somehow frowned upon.

The truth is almost the opposite.

Healthy spirituality and healthy sexuality have more in common than many people realize. In fact, a growing body of relationship research suggests that the very qualities that strengthen a person’s faith also strengthen emotional and physical intimacy in marriage.

At first glance, spirituality and sexuality may seem like two completely different parts of life. But in a healthy marriage, they are deeply connected. Great sex isn’t built only on physical attraction. It grows from trust, safety, acceptance, friendship, forgiveness, and selfless love. Healthy spirituality nurtures every one of those qualities.

Here are just a few examples.

Grace and Forgiveness

Holding onto resentment creates barriers between husband and wife. And without emotional intimacy, physical intimacy eventually suffers. Sex becomes little more than a physical act rather than a meaningful expression of love.

Forgiveness removes those barriers.

Relationship researcher Dr. Everett Worthington, whose work has focused extensively on forgiveness, has found that forgiving others reduces resentment and promotes healthier, more satisfying relationships. That’s exactly what happens in marriage. As forgiveness grows, emotional closeness often grows with it.

Grace also means learning to receive forgiveness.

When we refuse to accept forgiveness, guilt and shame often linger. Those emotions quietly convince us that we’re unworthy of being fully known or deeply loved. It’s difficult to experience genuine intimacy when shame is standing in the room.

Accepting your spouse’s forgiveness—and ultimately God’s forgiveness—clears away much of that burden and opens the door to a deeper connection.

Self-Sacrificial Love

For Christians, marriage is much more than a legal agreement. It is a covenant created and blessed by God. That understanding shapes how husbands and wives care for one another every day.

Instead of asking, “What can I get?” healthy marriages begin asking, “How can I serve?”

When you consistently place your spouse’s needs alongside your own, they feel loved, valued, and cherished. Those feelings naturally deepen attraction and strengthen intimacy.

Ironically, couples who stop chasing their own happiness and begin investing in each other’s well-being often discover that they become happier themselves.

Trust and Openness

A covenant relationship also creates safety.

When two people know they are committed for the long haul, trust has room to grow. That trust is strengthened through honesty, openness, and integrity.

Marriage researcher Dr. John Gottman has spent decades studying successful marriages and consistently found that trust and emotional connection are among the strongest predictors of lasting relationship satisfaction.

The same is true in the bedroom.

It’s difficult to fully trust someone who is secretive, dishonest, or emotionally unavailable. Those habits slowly erode intimacy.

But openness and honesty invite vulnerability. Vulnerability builds trust. And trust creates the kind of emotional safety where physical intimacy can flourish.

Bringing Spirituality into Your Marriage

So how do you experience these benefits in your own relationship?

Begin by accepting Christ’s forgiveness and grace. Receive His love, spend time with Him in prayer and Scripture, and allow His character to shape your own.

Then pray for your spouse each day. Ask God to bless them, encourage them, protect them, and show you practical ways to love them well. Couples who share meaningful spiritual practices often experience greater emotional closeness because their hearts are continually being drawn toward the same Source.

Finally, make a daily decision to reflect Christ’s grace in your marriage. Be quick to forgive. Choose kindness over criticism. Serve instead of keeping score.

Few things are more attractive than a husband or wife who consistently reflects the character of Christ.

And yes… one of the surprising blessings of that kind of marriage just might be a richer, more satisfying sex life.
