“For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the husband. Otherwise your children would be unclean, but now they are holy.”
1 Corinthians 7:14 (WEB)
Context Reading
12But to the rest I — not the Lord — say, if any brother has an unbelieving wife, and she is content to live with him, let him not leave her. 13The woman who has an unbelieving husband, and he is content to live with her, let her not leave her husband. 14For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the husband. Otherwise your children would be unclean, but now they are holy. 15Yet if the unbeliever departs, let there be separation. The brother or the sister is not under bondage in such cases, but God has called us in peace. 16For how do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?
