1 Corinthians 7:6

But to the married I give instructions, not I, but the Lord, that the wife should not leave her husband

But to the rest I say, not the Lord, that if any brother has a wife who is an unbeliever, and she consents to live with him, he must not divorce her.

Now concerning virgins I have no command of the Lord, but I give an opinion as one who by the mercy of the Lord is trustworthy.

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

I am not speaking this as a command, but as proving through the earnestness of others the sincerity of your love also.
