1 Corinthians 7:28, 32-34, 38

But if you decide to marry, that is not a sin. And it is not a sin for a girl who has never married to get married. But those who marry will have trouble in this life, and I want you to be free from this trouble.

I want you to be free from worry. A man who is not married is busy with the Lord’s work. He is trying to please the Lord. But a man who is married is busy with things of the world. He is trying to please his wife. He must think about two things—pleasing his wife and pleasing the Lord. A woman who is not married or a girl who has never married is busy with the Lord’s work. She wants to give herself fully—body and spirit—to the Lord. But a married woman is busy with things of the world. She is trying to please her husband.

So the man who marries his fiancée does right, and the man who does not marry does better.
