1 Corinthians 7:37-40

37But he who stands firm in his heart (who is under no compulsion, but has control over his own will) and has decided in his heart to keep her as his fiancée, will do well.

38So, then, he who marries his fiancée does well, but he who does not marry will do better.

39A wife is bound as long as her husband is living. But if her husband dies, she is free to be married to anyone she wants — only in the Lord.

40But she is happier if she remains as she is, in my opinion. And I think that I also have the Spirit of God.
