cinder; firstly, about HB”H, there are ways, it doesn’t take a few talks to convince someone, sometimes ppl are pushed away from believing in HB”H because they don’t see the G-dliness in ppl.
Although in nature it it as clear as day. By restoring the persons faith in people (i don’t mean actual faith) letting your Tzelem Elkm shine thru. Over time one can come around to acknowlege what their heart knows to be true.
Discussing stories of chassidim and tzaddikim, even if she doesn’t believe them, just to hear some strong concepts of Ahavas Hsm
and Emunas Tzaddikim in Hsm, can plant seed of awakening.
It might take time maybe years later, but if you let these
seeds of light enter her consciousness you may be directly
responsible for her being chozer bitshuvah many years later.
Even if she laughs at the stories…..
It WILL hit home!!!!!!!
2) you must support her strongly, (aside from it being wrong)
as you clearly state, He is trying to convince her to do a bunch of things “she does not want to do”
So tell her she should absolutely not do anything she does not want to do, or let herself be influenced to change her mind.
I don’t know how old you are but if you are old enough you can clearly convince her the pain and regret she will surely have not being able to undo things.
1)giving herself away to someone unworthy,
unworthy how? trying to persuade her to do things against her will. [Also pregnancy is an issue.] tell her to read stories
of how young girls unsuspecting had their lives turned upside down
and inside out ruining their youth etc…
I’m not sure what your asking as far as the step brother,
not knowing all the details, but if she is in real danger,
i.e he comes around threatening her, you should give her
the number of an abuse hotline.
