Sexual Morality

Don't Talk About It
Q: The Bible teaches people to abstain from “sexual immorality.” How am I supposed to know what this means?

A: This is a very observant question. There are a number of passages throughout the Scriptures that explicitly condemn "sexual immorality" without a description of exactly what this means. As a result, you will find a great range of answers to a question like this. Especially amongst different denominations.

Unfortunately, many of the disagreements in this particular area are not based on careful examination or exegesis of the Scriptures. They are really a product of personal preferences and cultural mores. While some of these "definitions" are probably better than others, it is always dangerous to allow our culture to interpret the Scriptures instead of the Scriptures interpreting our culture (Romans 12:1-2) -- especially when living in a "sex crazed" culture such as ours!

Sex is a touchy topic. Unfortunately, one that is not discussed much within the Church. That probably seems strange. But I mean exactly that: the Church should talk more about sex than it does. When the Church fails to allow the light of the revelation of God to shine in different areas, we should not be surprised to find that these same areas drift into darkness.

When a society moves into moral relativism (a direction in which the United States is moving further and further with each passing moment), sin abounds. We are not the first to "experiment" with doing what is right in our own eyes. Just take some time to read through the book of Judges sometime to see what can happen when everyone does what is right in their own eyes. It isn't pretty!

Instead of walking in the darkness, Jesus calls us to follow Him and walk in the light (John 8:12). The Church has been entrusted with the revelation of God (Jude 1:3). We are supposed to serve as the "pillar and support of the truth" so that believers may know how to conduct themselves, both in the Church and in the world (1 Timothy 3:15; 2 Timothy 3:16-17; Colossians 4:5). Therefore, when the Church stops teaching on sex, this important area of human experience drifts into darkness.

We sometimes think we are being "proper" by failing to talk about such things. But the Scriptures have a lot to say about sex! To fail to discuss matters relating to human sexuality is to fail to teach the full counsel of God.

Some think it is good and right to ignore topics relating to human sexuality. They believe that sex itself is inherently sinful. Some have even based this "teaching" on passages such as the following:

Behold, I was brought forth in iniquity, And in sin my mother conceived me. (Psalm 51:5, NASB)

However, this is not the best way to understand this passage. Instead, David is pointing to his depraved and fallen state. He is expressing that he himself was "in sin" from the moment of conception. He's not saying his conception was a result of a sinful sexual act by his parents. The whole Psalm is about David's personal guilt. The interpretation that this is describing "sex" as sinful is simply forced. The NET Bible has a good note on this passage which is worth quoting in full:
Heb "Look, in wrongdoing I was brought forth, and in sin my mother conceived me." The prefixed verbal form in the second line is probably a preterite (without vav [w] consecutive), stating a simple historical fact. The psalmist is not suggesting that he was conceived through an inappropriate sexual relationship (although the verse has sometimes been understood to mean that, or even that all sexual relationships are sinful). The psalmist's point is that he has been a sinner from the very moment his personal existence began. By going back beyond the time of birth to the moment of conception, the psalmist makes his point more emphatically in the second line than in the first.

To interpret this passage to mean that sexual intercourse is inherently sinful causes severe problems with the rest of the Scriptures. God created humanity in His image. He commanded that they be fruitful and multiply. This is a command to have sexual relations. That's how human beings reproduce. But, God does not command us to sin.

The New Testament teaches that it is not beneficial for married couples to abstain from sexual relations for a long period of time:

Now concerning the things about which you wrote, it is good for a man not to touch a woman. But because of immoralities, each man is to have his own wife, and each woman is to have her own husband. The husband must fulfill his duty to his wife, and likewise also the wife to her husband. The wife does not have authority over her own body, but the husband does; and likewise also the husband does not have authority over his own body, but the wife does. Stop depriving one another, except by agreement for a time, so that you may devote yourselves to prayer, and come together again so that Satan will not tempt you because of your lack of self-control.
(1 Corinthians 7:1-5, NASB)

Notice two things about this passage. First, Paul writes under the inspiration of the Holy Spirit that "because of immoralities, each man is to have his own wife, and each woman is to have her own husband." The solution to "sexual immorality" is not to abstain from sexual relations but to have a healthy sexual relationship with your spouse. In this passage Paul is explicitly teaching that the best antidote to sexual immorality is a healthy dose of moral sexual behavior within the confines of Christian marriage.

Secondly, Paul teaches that to abstain from healthy sexual behavior for too long is not a good thing. This creates opportunity for Satan to tempt us through our lack of self-control.

However, this still doesn't fully answer the question of what is "sexually moral" behavior. Paul seems to be operating on an assumption that his readers understand what is appropriate sexual behavior and what is not. He is not interested in giving a list of "approved sexual behaviors." In fact, the Scriptures consistently take this tact. The Bible never resorts to explicit uses of imagery or language that will arouse the various lusts and impulses of the flesh. The Scriptures are not meant to tempt us but to train us in righteousness and holiness and to point us to Christ.

As a result, we can have some difficulties if we are expecting that the Lord will simply provide a list of "approved" sexual acts. This would be borderline pornographic. We do not see such a list.

Some groups have made the error of attempting to validate certain sexual behaviors through finding "examples" of such behavior that are not explicitly condemned as sinful in the Scriptures. An example of this is the teaching that polygamy is a valid practice based on the actions of the Patriarchs (e.g. Jacob). This is a serious error. The Bible records faithfully the sinful acts of many people. It is sobering to realize that there is only one person in all of Scripture who was without sin: Jesus. Everyone else -- every "hero" of the faith -- is terribly sinful compared to a righteous God. To interpret what happened in the lives of sinful people, especially in narrative accounts, as what ought to happen is a mistake. A big one.

To make better sense of all of this, it is good to turn our attention to the heart of the question above. How are we supposed to know what "sexual immorality" is? The Scriptures define both negative ("Don't") and positive ("Do") commands and affirmations. To best understand the negative (abstain from sexual immorality) it is helpful to understand the positive; namely, what is the scriptural definition of "sexual morality"? If we know what is "sexually moral" then we know that anything outside of this is "sexually immoral." That's the stuff we're supposed to abstain from.

The definition of sexual morality is given very early in the Scriptures:
For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh.
(Genesis 2:24, NASB)

This is part of God's very good original creation. Man (both male and female, see Genesis 1:27) is to fulfill his purpose by multiplying over the face of the earth. Ruling over the earth and subduing it. So, there was given the institution of "marriage between a man and a woman."

One man, one woman, for the purpose of fulfilling God's plan.

Have you ever thought about the fact that the sexual relationship between a man and a woman is the most powerful creative act that human beings can engage in? The sexual act is the only way that the most amazing creation of our God (another human being) can be formed! No wonder this powerful act can be so dangerous when corrupted from its original design and intention.


If we understand this passage to be the definition of "sexual morality" -- i.e. the moral place for sexual relationships is within the monogamous confines of a relationship between one man and one woman -- then we can see that the Scriptures do not need to condemn polygamy when it is described later in Genesis (and throughout the Scriptures). It has already defined sexually moral behavior. Polygamy falls outside of that scope.

Likewise, if we understand that this is how the Scriptures define the moral sexual relationship, now we can understand the seeming "silence" of the Scriptures on issues like "premarital sex." I've heard some claim that the Bible doesn't ever condemn premarital sex. So, therefore, sex before marriage isn't part of "sexual immorality" they claim.

However, can you find a Scripture that defines a marriage ceremony like what we practice today? I bet you can't. Because there isn't one.

How does the Bible define marriage?

There are a number of passages that could be quoted. Perhaps the clearest is found in Deuteronomy 21:13b -- ...and after that you may go in to her and be her husband and she shall be your wife. (Deuteronomy 21:13, NASB)

This passage explicitly states that the consummation of the physical act of intercourse is what joins a man and a woman together as husband and wife. So why doesn't the Bible discuss "premarital sex"? Because there is no such thing!

The moment the physical act is consummated, the two are joined together in the eyes of God until the death of one or both partners. God is serious about sex.

Re-read Genesis 2:24 -- For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh.

There is no need for an "officiant." No witnesses are necessary. A party is completely optional. None of the normal stuff we associate with weddings is mentioned. Once they are "joined" they are one. This doesn't necessarily diminish the importance of a ceremony and the rest. But it does point to the fact that marriage is not the same in the eyes of God as it is in the eyes of our society. The ceremony is supposed to point to the commitment to stay faithful to each other. However, even our laws represent an understanding that the marriage is only valid if it has been consummated.

If this positive understanding of "sexual morality" is right, this helps us to understand the negative commands even more clearly. There are some things which God commands that be refrained from even within the confines of marriage. The Law recorded several prohibitions regarding sexual conduct that applied to the nation of Israel in particular. The Church is no longer under the Law. But these principles are still valuable for us to understand (2 Timothy 3:16-17). Space does not permit us to examine each of these in great detail. It is worth a prayerful read through the Pentateuch (i.e. the first five books of the Hebrew Bible: Genesis, Exodus, Leviticus, Numbers and Deuteronomy) to see how God discusses sexual relations between husbands and wives.

There is one final aspect of Scriptural teaching in the New Testament that must be understood as it relates to "sexual morality." Jesus defined the 7th Commandment to be more than simply the outward act of marital unfaithfulness. He extended it even to the thoughts and intentions of 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 lust for her has already committed adultery with her in his heart. (Matthew 5:27-28, NASB)

Simply put, this means that God intends for 100% of all sexual fulfillment to be had within the confines of the marriage relationship. This includes physical, emotional, and mental fulfillment. Since this is the case, it makes even more sense why God would inspire Paul to write what was already quoted above from his letter to the Corinthians:

But because of immoralities, each man is to have his own wife, and each woman is to have her own husband. The husband must fulfill his duty to his wife, and likewise also the wife to her husband. The wife does not have authority over her own body, but the husband does; and likewise also the husband does not have authority over his own body, but the wife does. Stop depriving one another, except by agreement for a time, so that you may devote yourselves to prayer, and come together again so that Satan will not tempt you because of your lack of self-control. (1 Corinthians 7:2-5, NASB)

Sex is not sinful by itself. It is a good and powerful thing, created by God. It is not wrong to be enjoyed. In fact, there is an entire book devoted to the joy of sexual morality in the Scriptures: Song of Solomon. As a result of the overtly sexual nature of this book, it has been debated as to whether or not this belongs in the Scriptures. Once it was decided that it would be inappropriate to remove this book from the canon, various "spiritual" interpretations were suggested. These spiritualizations try to make the book about something other than sex. Most often, as an allegory for Christ and the Church.

I am in agreement with John MacArthur about the proper interpretation and handling of Song of Solomon. MacArthur wrote a good 5-part blog post (the first part is available here, and the interested reader can find the links to the next parts at the bottom of that page) in response to the opposite error of making the Song a "how to manual" with commands to engage in certain explicit acts by another famous pastor. MacArthur's article series is worth reading in its entirety.

The major point is this: the Scriptures define "sexual morality" as the complete (100%) fulfillment of all sexual activity (whether physical, emotional, or mental) within the confines of a marriage between one man and one woman. Other scriptural prohibitions regarding sexual activity should therefore be understood as applying to the marriage relationship and further defining and restraining sexual fulfillment. These restrictions are not meant to prohibit sexual activity. Instead, they are meant to properly focus all sexual activity in a way that is God-honoring and holy. Failure to operate within these parameters as created by God is to be "sexually immoral."

Sex is a gift from God. When understood and used properly it is a beautiful thing. It is the most powerful creative act that human beings can engage in. It is also extremely dangerous when perverted and used outside of the parameters of "sexual morality."

Hopefully, this helps shed some light on this topic so that you may walk in holiness and purity before your God!

Good job P. Joe. It is interesting that when mankind rejects God's truth, the wrath of God becomes evident in darkened hearts that become sexually immoral as a result. A good read of Romans 1:18-32 shows the results of "moral relativism" as well...when "suppression of the truth" leads to "futile speculations" and "darkened hearts".
It is also interesting that when God (in His wrath against sin) "gives mankind over" to the "lusts of our hearts", or to do what seems right to us, things never get better. Instead,sexual immorality, depraved minds, and general unrighteous behaviors abound.

Excellent points, especially in bringing up Romans 1:18-32. Thanks, P. Scott!

Thank you for this discussion regarding sex and it being appropriately confined within a "marriage". But you indicated that God views a couple as married once they have sex. So what happens in the case of premarrital sex with multiple partners? Is a person only considered married, in God's eyes, to the first person they had sex with? What happens if someone, that's a virgin, has sex with someone that's not? Should the former consider themselves married while the later considers it an adulterous affair? There must be a Scriptual answer to this can-of-worms.

Hi Anonymous,

Thanks for stopping by!

You asked some really good follow-up questions. I will try and write a new post addressing the issues you raised as soon as possible.

Take care,

Prayer vs. Petition

Q: What's the difference between prayer and petition? Phil 4:6 for example.

A: An excellent word study question! When attempting to study words from the text it is necessary to analyze the word being studied in the original language (in this case Greek) as attempting to look up the words in English will often produce erroneous results.

For example, in English the word petition has within its range of meanings things that are certainly not within the scope of meanings for the Greek word (i.e. “a sheet that is signed to demonstrate agreement with some principle or desire for some social action to be taken” is part of the range of “petition” but not of the Greek deesis from which “petition” is translated).

The word most commonly translated as “prayer” in our English Bibles is proseuche, which appears 36 times in the New Testament (NT) in one form or another (for the purposes of this study, we are only examining the usage of these words as nouns – the verbal forms will not be included…

Christianity Isn't Moralism

Do this. Don't do that.

Shop here. Don't shop there.

This is acceptable. That is an abomination.

Don't get me wrong. Christianity does have a moral code. That's undeniable.

And that moral code is not popular. Not by a long shot. The Bible is clear that the moral code is contrary to the flesh. By definition it goes against the grain of fallen human nature.

But Christianity isn't moralism.

The moral code is not the end. It's only a diagnostic. The Bible calls for rebels against the King of heaven and earth to be reconciled to Him through His Son, Jesus the Christ. The Bible calls for people to turn from their rebellion and live for Him. This means that we stop pursuing the various lusts and impulses of our flesh. It means we start living in obedience to our King. We live for the glory of His name.

The diagnostic helps us to see that we are off track. But living according to some external sort of rules is not the end goal. That was the mistake the Pharisees made. Yo…

Christ Died For Our Sins

For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures
(1 Corinthians 15:3)
The truth of the gospel includes this important phrase: Christ died for our sins.

You've probably heard it before. Many times.

Sometimes familiarity leads to a diminished sense of importance. The more you hear about something the more ordinary it may seem. Common. Ho-hum. Boring.

But this truth is anything but common.

Another difficulty arises with this truth. Beyond being common. It may happen in your ears without you even realizing it.

When the truth is declared that Christ died for our sins, you may think you hear the truth. But what you really hear is a diminished version. A partial truth.

Instead of hearing that Christ died for our sins you may hear a slightly different version of this truth. You might hear this: Jesus died for your sins.

Do you see the difference? You should.


These statements are similar. Both may very well be true…

Hallowed Be Thy Name

Growing up, I said the Our Father prayer a lot.

A lot. Multiple times a day.It was part of my religious tradition. Most of the time, I mumbled it as quickly as I could.

For what it's worth, my Dad tried to help me understand that mumbling the prayer without understanding what it really meant wasn't the goal. He wanted me to understand it. He wanted me to mean it.

I remember sitting with him in the car one afternoon while we went through every phrase. He did his best to explain to me what the terms meant. Why we would say these things. Why it mattered.

It didn't take.

Although I became better equipped to describe the meaning of the phrases, I still mumbled them as fast as I could so I could move on to the next part of my day.

Fast forward many years. After being born-again by the grace of God I started to read my Bible. I desired to know God and His Word. I remember when I stumbled upon Jesus teaching the disciples to pray the Lord's prayer in Matthew 6. I was both excit…

Self-Centered Theology

I have a problem.

Maybe you do, too.

I bet you can at least relate.

I'm self-centered.

By nature, I think from my perspective. Often, more often than I'd usually like to admit, I pursue my agenda.

I like to do, what I like to do, when I like to do it, where I like to do it, how I like to do it, and with whomever I like to do it.

I think you do, too.

Sometimes we are good at hiding this self-centeredness. I believe that it is possible to have genuinely altruistic moments. Moments where we put others self-interest above our own well-being. Sometimes powerful emotions like love, hate, and disgust, can cause us to act contrary to our self-centered notions.

Sometimes.

As Christians, we are given the gift of God's grace through His Son, Jesus Christ. We receive this gift when we repent of our self-centered ways and trust in Christ alone. In the noise that is "Christianity" - if you take the time to really listen - you will often hear a false gospel that appeals to the …
