Christians is it true a woman living with her boyfriend will still go to heaven if she attends church?

You are uming she is sleeping with the boyfriend she's now living with. If so, that's fornication and not to be taken lightly. In fact, in Acts 15 it says it's one of the few things outlawed specifically in the new group of people to be called Christians later on. She's been misinformed and though her leaders will answer for it, it's her soul that's gonna feel it worst of all. A marriage is a commitment. And if he won't commit, she's in trouble.
