1 Cor 7:16

7:16 whether you will save. Paul may be returning to the thought of v. 14 and giving a reason why Christians should not leave their unbelieving spouses: since they are in some sense “sanctified,” there is a good possibility that they will be saved. Alternatively, v. 16 may explain v. 15: let the unbeliever go, because you have no assurance that he or she will be saved by being forced to stay married.
