Friend's Family Troubles

I have an old friend that is... for lack of a better term having some family troubles.

Her family is, to my knowledge not generally a family of believers. If her parents do believe I don't think you'd be able to tell if you spent a day with them. I'm not attempting to judge them, I just don't really know a more delicate way to put this, I don't know about their salvation. Not my call anyway... And I'm not saying any of this all furrow-browed, just to give you guys some background with the situation.

I digress...

My friend (we will call her Lucy), is 23 and currently living at home where she's trying to get a job and move out. Her sister is about 12 or 13 (can't remember, definitely no older than 14...) and has been a huge source a trouble for the family. It's really a pretty wild situation. She spends a lot of time online in in very sexual situations. I've seen some of her conversations and I didn't know kids this young had this kind of language. She has cyber sex or whatever fad she's doing these days with quite a few people. (Apparently she recently had a 20ish year old guy come visit her from upstate like 6 hours or something) It's possible she has recently become sexually active(She has been seen taking nude pictures and being groped by her boyfriend and has largely remained unpunished). She's been known to cut herself and she is often absolutely disrespectful to her family in language and action. This stuff has been going from an age where I probably wouldn't have even known sex was a thing.... I mean... it's been going on for years.

Lucy, my friend, is about the only one in the family that even seems to take any sort of action. She has talked to the parents and they will either blame Lucy saying that it's her fault because since she spends a lot of time online that her sister has learned all of this from her and then make no effort toward the younger sister. Or they will tell Lucy to "be a sister and spend time with her" which has obviously not worked. The situation came to a head once about a year ago when the younger sister claimed to be a lesbian and in a relationship with a girl of a... less than admirable reputation.

The two young girls were apparently cutting each other (I don't understand this epidemic among preteens/teens but it's seriously awful.) and my friend's parents filed assault charges against the girl. They went to court I don't know how the case turned out. A lot happened, my friend talked to the school counselor and researched some stuff and found something like that if the parents aren't actively abusing the child all they can do is give counselling and even then I think the parents have to agree... That's probably not 100% correct I can't remember the exact details.

aaanyway. She went to counselling for a while and it's been like a year (give or take) and it's not getting better, it's possibly getting worse. The most the parents have done other than blaming Lucy or filing charges against the other girl is tell her to get off the computer for a bit. Then she often refuses to and nothing happens. They actually bought her a laptop so now she goes into the privacy of her room with it, which is what she has been doing with the phone/s her parents keep getting for her.

I really don't know what can be done other than to pray that everyone involved would see Jesus and take proper actions. Like I said, I don't know what the parents believe. Lucy doesn't seem to think religion much, so I'm trying to share the gospel with her. The most the younger sister has shown is that she wanted to go to a church to meet some boy or something

It's really awful. When I first heard about it I thought for sure it was an exaggeration, but then I've seen a lot of it firsthand and as bad as I make sound I would probably say it's worse.
It's really sad that someone this young isn't being taught what's right and wrong. A child this young/untaught should not even be trying to have relationships especially with so many people, many of them strangers, and many/most/all of them based on sex (whether or not she's had intercourse... it's a main focus)

So yeah. I don't know what can be done but hope that they will accept Jesus, for the sake of themselves and for the child.

Praying for the whole situation and that God may give you some wisdom in whats best to do.
