If the Bible addresses an issue with unrelenting frequency and urgency, and if that issue is one of the strongest natural forces in the world today, then ministers of the Word of God are obligated sooner or later to declare God's will on that issue. The sexual life of the unmarried person is of great concern to God. Even those of you who have not entrusted yourselves to Christ for salvation and do not love God, even you are obligated to obey what God has to say about your sexual desires. Though you rebel against his ownership, you are God's. He made you and has an absolute right to tell you what is good for you. He sent Jesus Christ into the world to overcome your rebellion and to make peace by the blood of his cross. And my prayer at the very outset is that you might turn from your rebellion and unbelief and disobedience, and that you might trust Christ for forgiveness and live for the glory of God.

Your Body Is Not Your Own

Then I would be able to say to everyone in this room, do you not know that your body is the temple of the Holy Spirit, within you, which you have from God? You are not your own; you were bought with a price. So glorify God in your body (1 Corinthians 6:19, 20).

O, what an offensive word to our rebel human nature. The body in which you dwell is not yours to do with simply as you please. God bought your body from the curse of sin by the payment of his own Son, and now your body should serve one all-encompassing purpose: "Glorify, God in your body." As Paul said in Romans 6:12–14,

Let not sin therefore reign in your mortal bodies to make you obey their passions. Do not yield yourselves to sin as instruments of wickedness, but yield yourselves to God as people who have been brought from death to life, and your bodily parts to God as instruments of righteousness. For sin will have no dominion over you, for you are not under law but under grace.

God is concerned about what you do with your body. He created them, he bought them, he owns them, he indwells them, and what we do with them demonstrates to the world who our Lord is. If I were to stop here with this general admonition, our consciences would give us some guidance in specific cases, say, of whether we should smoke, or drink, or use drugs, or overeat, or never exercise, or get too little sleep, or engage in sexual relations outside marriage, or masturbate, or wear enticing clothing, or other things that misuse or abuse the body. But what our consciences approve and disapprove of is not always an accurate guide to what God approves of. Therefore, the Bible goes beyond the general admonition, "Glorify God in your body," to the more specific guidance, especially in the matter of sexual desires. So I aim to be more specific, too.

Why Did God Invent Sexual Desire?

The question I want to start with is this: Why did God invent sexual desire? Before I try to answer that question from Scripture, let me define sexual desire. First of all, I am not including homosexual desires. Until I have a chance to preach on homosexuality I'll just say three things about it:

1. If you are here and homosexual, I pray that you will not feel driven away, but will stay and seek help.
2. The practice of homosexuality is sin; it is contrary to God's revealed will.
3. Homosexual desires, like many other kinds of desires, are abnormal, and those who have them should seek through prayer, fellowship, and Christian counseling to be changed. It is not easy, but it is possible.

When I ask the question, why God created sexual desire, I have in mind that normal craving for sexual stimulation and intimacy that begins with early adolescence and continues, for some it seems, indefinitely, but for many mellows out into a less visceral craving but nevertheless real desire for personal and bodily intimacy. I acknowledge that in these years of sexual desire there are many people with very vigorous, and people with very mild, sexual desires. I don't mean to treat anyone along this continuum as better or worse than another. When I speak of those with sexual desires I refer to the vast majority of people who from their early adolescence have to deal one way or another with God-given sexual appetite.

Now, why did he create it? Let me give one brief answer and one expanded answer. The brief answer comes from Genesis 1:27, 28, "God created man in his own image, in the image of God he created him; male and female he created them. And God blessed them, and God said to them, 'Be fruitful and multiply and fill the earth and subdue it."' Since sexual desire aims finally at consummation in sexual intercourse, and sexual intercourse is the means that man and woman have of multiplying and filling the earth, therefore, I infer that one of the reasons God created us with sexual desire is to see to it that mankind would indeed fill the earth with people. And for some people procreation of children is the only justification for seeking gratification of sexual desires. But we will see in more detail next week, when we talk about sexual relations in marriage, that the apostle Paul has quite a different view.

A second answer to the question, why God created sexual desire, is found, I believe, in 1 Timothy 4:1–5,

Now the Spirit expressly says that in later times some will depart from the faith by giving heed to deceitful spirits and doctrines of demons through the pretensions of liars whose consciences are seared, who forbid marriage and enjoin abstinence from foods, which God created to be received with thanksgiving by those who believe and know the truth. For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving, for then it is consecrated by the word of God and prayer.
