1 Corinthians 7:12-14Holman Christian Standard Bible (HCSB)
12 But I (not the Lord)[a] say to the rest: If any brother has an unbelieving wife and she is willing to live with him, he must not leave her. 13 Also, if any woman has an unbelieving husband and he is willing to live with her, she must not leave her husband. 14 For the unbelieving husband is set apart for God by the wife, and the unbelieving wife is set apart for God by the husband.[b] Otherwise your children would be corrupt, but now they are set apart for God.
