“Do not deprive each other of sexual relations, unless you both agree to refrain from sexual intimacy for a limited time so you can give yourselves more completely to prayer. Afterward, you should come together again so that Satan won’t be able to tempt you because of your lack of self-control. I say this as a concession, not as a command. But I wish everyone were single, just as I am. Yet each person has a special gift from God, of one kind or another.” 1 Corinthians 7:5-7
The principle in this passage is important. God makes it clear that there is nothing wrong, and everything right, about sex in marriage. Satan’s great strategy, when it comes to sex, is to do everything he can to encourage sex outside of marriage, and to discourage sex within marriage. It is an equal victory for Satan if he accomplishes either plan. This can be seen in the way some of the Corinthian Christians thought it was just fine to hire the services of a prostitute, and other Corinthian Christians thought it was more spiritual for a husband and wife to never have sexual relations. A Christian husband and wife must not accept a poor sexual relationship. The problems may not be easily overcome or quickly solved, but God wants every Christian marriage to enjoy a sexual relationship that is a genuine blessing, instead of a burden.
Satan, who knows the temperament and disposition of men and women, may tempt them not only to hatred of, and quarrels with one another, but to impure lusts and desires, to fornication, adultery, and all uncleanness; a very good reason why, though abstinence from the marriage bed for a short time, by the consent of both parties, for religious purposes, may be lawful, yet ought not to be continued; since Satan may hereby get an advantage over them.
