Should a believing spouse stay married to an unbelieving spouse?


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. And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him. For the unbelieving husband has been sanctified through his wife, and the unbelieving wife has been sanctified through her believing husband. Otherwise your children would be unclean, but as it is, they are holy.
But if the unbeliever leaves, let it be so. The brother or the sister is not bound in such circumstances; God has called us to live in peace. How do you know, wife, whether you will save your husband? Or, how do you know, husband, whether you will save your wife? 1 Corinthians 7:12-16
            Yes, absolutely.  Not believing in God is not a reason for divorce.  That spouse has access to the other spouse’s heart and can show Jesus in their life.  As long as the spouse is willing to stay married, then stay married.  Walking away from the marriage will show hate and judgment to the unbelieving spouse who would then start resenting God.  The best way for the unbelieving spouse to experience Jesus would be through the believing spouse showing love and grace.
            The Bible allows divorce only if the unbeliever leaves.
