1 Corinthians 7:32-40

Because of this, we need to live as free from anxiety as possible. For a single man is focused on the things of the Lord and how he may please him. But a married man is pulled in two directions, for he is concerned about both the things of God and the things of the world in order to please his wife. And the single woman is focused on the things of the Lord so she can be holy both in body and spirit. But a married woman is concerned about the things of the world and how she may please her husband. I am trying to help you and make things easier for you and not make things difficult, but so that you would have undistracted devotion, serving the Lord constantly with an undivided heart. However, if a man has decided to serve God as a single person, yet changes his mind and finds himself in love with a woman, although he never intended to marry, let him go ahead and marry her; it is not a sin to do so. On the other hand, if a man stands firm in his heart to remain single, and is under no compulsion to get married but has control over his passions and is determined to remain celibate, he has chosen well. So then, the one who marries his fiancée does well and the one who chooses not to marry her does better. A wife is bound by the marriage covenant as long as her husband is living. But if the husband dies, she is free to marry again as she desires—but, of course, he should be a believer in the Lord. However, in my opinion (and I think that I too have the Spirit of God), she would be happier if she remained single.
