1 Corinthians 7:13-15

New Living Translation

¹³ And if a believing woman has a husband who is not a believer and he is willing to continue living with her, she must not leave him. ¹⁴ For the believing wife brings holiness to her marriage, and the believing husband^[a] brings holiness to his marriage. Otherwise, your children would not be holy, but now they are holy. ¹⁵ (But if the husband or wife who isn’t a believer insists on leaving, let them go. In such cases the believing husband or wife^[b] is no longer bound to the other, for God has called you^[c] to live in peace.)
