We read about principles for marriage in 1 Corinthians 7:
Now concerning the matters about which you wrote: “It is good for a man not to have sexual relations with a woman.” But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband. The husband should give to his wife her conjugal rights, and likewise the wife to her husband. For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does. Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.
Satan does not create sexual desire. It is good and he never produced anything good. His whole aim is to ruin what God created to be good. There are two ways you can ruin a pearl. You can cut it out of the oyster before it matures or you can feed it to the swine. Satan does his best to cut off sexual desire from the oyster of God’s grace and truth. If he can get people to isolate sex from the reality of God, he has virtually destroyed its true meaning and beauty. He also does his best to take the pearl of sexual desire and, instead of putting it in the pendant of marriage, feed it to the swine of fornication and adultery and pornography and incest and child abuse and homosexuality.
But the pearl of sexual desire is meant to grow and come to its full beauty in the grace and truth of God, its maker, and then be taken and placed in the golden pendant of marriage. Or, for those who are called to go the way of celibacy, the pearl of sexual desire is meant to be a kind of atomic ball-bearing in the wheels of human creativity.
Pitirim Sorokin, a professor of sociology at Harvard, and J.D. Udwin did a study in social history which concluded that “the periods of sexual liberty were the poorest from a cultural point of view, whereas those periods when morality and social convention imposed restrictions on sexual activity were the richest in creative output” (Christianity Today, Nov. 23, 1984, p. 29).
But Satan will use anything he can to ruin this pearl of sexual desire by cutting it off from God’s grace and truth, or feeding it to the swine of adultery and pornography, or keeping single people from putting its energy to use in a life of creative endeavor for the cause of Christ.
