1 Corinthians 7:39-40

39If a woman has married, she may not leave her husband while he still lives. But if he dies, then she is free to marry again. She may marry any man that she wants to. But he must be someone who belongs to the Lord.

40I do think that she would be happier if she remains without a husband. That is what I think, and God's Spirit also helps me with this.
