“For the unbelieving husband is sanctified through his believing wife, and the unbelieving wife is sanctified through her believing husband. Otherwise your children would be unclean, but now they are holy.”
1 Corinthians 7:14 (BSB)
Context Reading
12To the rest I say this (I, not the Lord): If a brother has an unbelieving wife and she is willing to live with him, he must not divorce her. 13And if a woman has an unbelieving husband and he is willing to live with her, she must not divorce him. 14For the unbelieving husband is sanctified through his believing wife, and the unbelieving wife is sanctified through her believing husband. Otherwise your children would be unclean, but now they are holy. 15But if the unbeliever leaves, let him go. The believing brother or sister is not bound in such cases. God has called you to live in peace. 16How do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?
