1 Corinthians 7:13-16

13Also, a Christian woman may have a husband who does not believe in Christ. If he agrees to continue living with her, then she should not leave him.

14God accepts a husband who does not believe in Christ because of his Christian wife. And God accepts a wife who does not believe in Christ because of her Christian husband. If that was not true, the children would not belong to God. But God does accept them, because to him they are now clean.

15But the husband or wife who does not believe in Christ may want to leave. If they want to become separate, let them do that. If that happens, the Christian man or woman is now free. God wants you to live in peace.

16If you are a Christian wife, you might save your husband. If you are a Christian husband, you might save your wife. But you can not be sure of what will happen.
