In chapter 7, Paul answers the question of “Is it a good thing to have sexual relations?”
Of course, he says, within the context of a marriage between man and woman. Marriage can provide a balanced and fulfilling sexual life in a world of sexual disorder, Paul says. Each partner can seek to satisfy the other and serve the other, which is a beautiful thing.
On the other hand, it is a good thing to be single, if that’s what you’re called to. You can focus on God, without the complexities of marriage. That’s not to say marriage is bad though. It’s a good thing to be married, if that’s what you’re called to. Paul encourages those who are single to stay in that state, and learn contentment in it. Similarly, he encourages those who are married to stay in that state, and learn contentment in it.
It’s obvious after reading chapter 7 that Paul refers singleness, but as he says,
God gives the gift of the single life to some, the gift of married life to others.
If you want more details — like how to handle being a virgin, how to handle being married to an unbeliever, how to handle death of a spouse, etc. — I won’t mention them all here. Just go read chapter 7 and I’ll catch up with you on chapter 8.
