This might be wierd, but i hope you hear me out, neither do i know your Daughter nor her Future plans or intentions, since im guessing you know her good, you can tell wich way she will go, she might of heard and listend to the Gosple all her life and all of it is still stuck in her head but people like we all are sinners, neither do i know if your Daughter nor you know about the Difference between Living in the Spirit or by the Flesh, nor if your Daughter ever talked or mentioned to you that she wants to become a Deciple of Jesus Christ or live a Worldly Life.
But lets take both in perspective and asume the worst then best, asume your Daughter chose that as soon as she got out of the House she will start to add everything in her life that she couldnt under your Rules, worldy things, she will try and get the most out of "life" meaning, partying, friends, drugs, alcohol, boyfriends ect....now although she knows the Gosple and knows it isnt right, her sense of "Liberty" and "Freedom" wich Satan clearly will take advantage of has gottan over her and sweeping her away into this world, and all that she knows about the Gosple now is swept aside, not forgoten nor lost, but swept aside, kept aside. At this point there are many things you can do, and i hard many Testimonies of Teens in the same situation, some of the teens in the same situation after living such a life for months and years finaly understand that there is a Void in them, that they tried to fill, and thought in the beginning that getting all that this "worldly life" has to offer should be more then suffecient to fill and add all that is needed to fill all Void in man/women. But they see themselfs and compare there current life with the life they had in there Families home "Hopfully Godly" and notice that the Void started to apear slowly after leaving not only the Family Home but leaving the Word "Bible" itself. This is a breakthrough but will still have to make hard choices, but since its really hard to recover from such a lifestyle and sometimes dont dare to repent, they take more drugs, more alcohol and more partying in believe "this should fill the Void" if it doesnt kill them they will notice nothing has changed, the Void in them is still there, thats were the person starts to repent if he chooses and get to know Jesus Christ, his Peace, giving freely to everyone that comes to him a sound mind and spirit with living water so they may never thirst again in a whole new different light, and there faith in the truth will become very strong.
on the other Hand if your Daughter mentioned to you at some point that she wants to follow Jesus Christ and wants to continue learning, growing in faith and knoweldge, then you shouldnt be worried at all at the moment, she is still a sinner and a lie here and a lie there wich shouldnt be, but if done, gives no reason to believe that your Daughter will throw away all her intentions once she goes out of the home, if she lied about her friend or the money. In that case forgive her, help her, pray for her.
There are some Christians who will Repent from such a life, but there are some who died in that life. If i were you, again this will sound harsh, is to pray that Jesus Christ will do everything neccassary even cause Pain, Sorrow or even Demonic Oppression to your Daughter that she might Cling onto the Lord Jesus Christ forevermore. All man React to Pain and Sorrow, some react to there Faith and Believe, some React to a Vision or Dream, some react to there Calling, some will ignore all and will react to none and choose Death, wich is just Rebellion. So Pray if you believe your Daughter is in Danger, pray that Jesus Christ will do everything neccassary so that your Daughter wont even Dare to consider doing anything without him.
Hope i Helped
