1CO 7:16

16 [You women believers should allow your unbelieving spouses to leave you if they want to], because there is no way that you can be sure that God will save your husband if you stay together [RHQ] (OR, perhaps God will save your husband if you stay together.) Similarly, you men [who are believers], there is no way that you can be sure that God will save your wives if you stay together [RHQ] (OR, perhaps God will save your wives if you stay together.)
