I say this as a concession, not as a command.
I wish that all of you were as I am. But each of you has your own gift from God; one has this gift, another has that.
Now to the unmarried and the widows I say: It is good for them to stay unmarried, as I do.
But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion.
To the married I give this command (not I, but the Lord): A wife must not separate from her husband.
But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.
To the rest I say this (I, not the Lord): If any brother has a wife who is not a believer and she is willing to live with him, he must not divorce her.
