Sex and Marriage

Several weeks ago I wrote a blog entitled “What God Thinks About Your Sex Life.” Since that post, I’ve had some follow-up thoughts that I have decided to add here.
I don’t know if you’ve ever thought about this, but God designed sex in kind of a weird way. Depending on the context, sex can have two completely opposite effects. Within marriage, sex can make a marriage stronger, but outside of marriage it is just the opposite. Rather than make a dating or engaged couple stronger, sex can actually tear the couple apart.
Perhaps one of the best analogies for this principle can be seen in a fireplace. When a fire is built inside the fireplace, it heats the whole home and keeps everyone warm. Prior to the age of electric heated homes, this was a life saving gift during winter. But if you take that same life-giving fire out of the fireplace, it will burn the house down, destroying everything and everyone within it.
It is the same with sex. Marriage is the hearth that contains the flames of sexual passion. When taken outside that protective guard, it has the power to destroy.
But why is that? Why is it that, in one context sex builds up, and in another context sex tears down?
To answer this question, we must first recognize the fact that most people, even many married people, have a fundamental misunderstanding about sex. We see it as a right, not a responsibility.
Think about it this way–the way that Christians frequently articulate the nature of sex within marriage is that all bets are off once you say “I do.” As soon as the ring is on the finger, your bodies belong to one another so you can and should do whatever crazy sexual stuff you want, as long as it’s legal. And the more sex you have, the better.
For example, I heard about a church in Texas in which the pastor gave his married listeners a homework assignment as follow-up to the sermon–every night that week, they had to have sex. That is the Christian culture we live in right now.
What is somewhat problematic about this mentality is that it flirts with the idea that sex is a right. In a Christian form, it sells the worldly mentality that we all deserve sex whenever and however we want. That is the perspective driving the homosexuality debate right now–Americans believe they have the right to life, liberty, the pursuit of happiness, and sex. And anyone who stands in the way of you having sex the way you want it is either a religious fundamentalist or a chauvinist.
But sex is not a right. It’s a responsibility. When two people engage in sex, they put one another in a position of extreme vulnerability, which means they are in a position to get hurt more than ever before. That’s why affairs are so devastating. But when two people have sex they ALSO create the possibility of conceiving a child. Those are high stakes!
And that’s why it’s important to guard sex no matter where you are in life. Whether you are married or single, it’s not as if anything goes. Sex is still a responsibility, and it should be treated as such. That is what I love about the natural family planning method of birth control. It requires that a married couple abstain from sex once a month when the woman is most likely to get pregnant. It demands that the couple make a sacrifice and step away from the act of sex to reflect on the responsibility that it involves. It prevents them from taking sex for granted.
When married couples forget the significance of sex, they are tempted to use abuse it just as much as single people. Maybe a husband begins to see his wife more as an object to used than a gift to be treasured and romanced before she gives herself to him sexually. If she does not give him his right to sex, he may even go looking for it elsewhere. Conversely, a wife might withhold sex from her husband as a form of manipulation.
Yes, sex must still be guarded within marriage because it can very much be abused.
But what does this mean for single people? Given that sex is such a powerful force, even within the hearth of marriage, it has an even greater potential to destroy when taken outside of that context. Why? Because having premarital sex means you have altogether bought the lie that you deserve sex whenever you want it. And when you engage in that kind of perspective, sex becomes a false idol.
Maybe it’s not an idol at first. Maybe it begins with you messing around with your boyfriend from time to time. Slowly, you two push the line back further and further and further. You’re no longer going too far once a week–now it’s almost every night. And one day you push the line back all the way. You have sex.
But don’t think the story ends there. Soon you find yourself justifying the sex. “I really love my boyfriend” or “I know I’m going to marry him” or “There are worse sins than this one.” Eventually you reach a point at which it no longer bothers your conscience. You have altered your entire system of faith to suit your sexual practice. Now, your life and your beliefs center around your sex life. Your interpretation of Christianity has been perverted or ignored to serve your sexual needs.
That is the definition of idolatry–when you center your life around something other than Christ. That doesn’t mean you’re a sex addict, it just means your sexual desires hold rank over God.
And that is the key difference between sex in marriage and sex outside of marriage. One stems from a life centered around idolatry and a need to satisfy one’s own desires. The other stems from a life centered around God.
And that is why one practice is more likely to bring life, whereas the other is likely to destroy. Whenever any practice or belief supplants the centrality of God in our lives, then we are headed towards self-destruction.
No matter where you are in life, married or single, that should be your theology of sex. Sex should always be practiced in a way that draws one another closer to God. This can ONLY be done in marriage, but it is not necessarily done in marriage. It is a discipline, and it is a form of worship so we must keep it sacred. Take the steps to guard it as such.

I recently received an e-mail from a young woman who loves her career but is getting married soon and wonders how her job will fit with her family. If she’s going to have kids one day and stay at home with them, then why bother building a career now? Is it even worth it?
I am blessed to have a friend in my life who is not inhibited by social graces like tact. If I ever need an opinion, I can depend on him to speak hard truth into my life, generally in the most blunt form possible. Fortunately, he is almost always dead-on in his observations, which is why I go back to him again and again, regardless of the form in which his wisdom is dispensed.
For many women, the idea of trusting a man TOTALLY in marriage is a scary thing. It’s not that their husbands aren’t trustworthy or that they don’t trust their husbands in some things. But the idea of submitting when you think you’re in the right, or when something really life-changing is on the line? That can be hard.
Think back to the movie When Harry Met Sally. In case you haven’t seen it, the film came out in the late 80’s, and it co-starred Billy Crystal and Meg Ryan. The storyline spans a period of many years beginning with the couple’s initial meeting, and following them as their friendship blossoms into romance.
But what was even more surprising is that we all enjoyed it, including myself! Since all the sex had been edited out, I was able to focus more on the plot line which, at its core, is about the unshakable bond between friends.
There is a similar phenomenon with the show Entourage. Here again, we see a group of guys who live the kind of life most guys only dream about. But what’s even better is that they live this dream life together. Unlike many people, they have not attained success only to find themselves alone at the top. Instead, they remain a solid core through the adventures of life. And like Sex and the City, each guy is different, offering his own unique personality to make the group what it is. Again, each man is free to be himself, and still be accepted.
