well, i can share with you what God was teaching me and still does. I was a single mom raising my kids for over ten years. Two boys. When i first came back to christ my kids did not exactly feel the same as i did. My older son at the time was like 13 and did not want to go to church, so i said you can go one day and not two days out of the week. Anyways, after a while, and lots of prayer, He was born agian, saved. But i did make him to go a camp once with the church, and that was a turning point. he did not want to go, and when he came back, he was changed. Praise God. Don't give up. I will tell you what i did and still do, i pray for my boys all the time. Start spending maybe more time in prayer, not that you don't, but the things you want to see change in your life and your family, ask God for those things and than watch the beauty of the Lord unfold right infront of your very eyes. Don't worry sis, God is faithful even when we are not. One of the best gifts you can give your child is jesus. spend some devotional time before bed.ask her if you can pray with her, and share some scripture. you can read a verse or two before she goes to bed. God's word changes us and His holy spirit. Here is a great verse for you sis....
Isa 55:11So shall My word be that goes forth from My mouth; It shall not return to Me void, But it shall accomplish what I please, And it shall prosper [in the thing] for which I sent it
So even if you think she is not listening, her spirit is. I would pray with both of my sons before bed, and they loved it, even if we were having a bad night. Know as christians we are going to have spiritual battle in our homes because satan loves division, so somtimes we have to stop and pray when things are getting kind of crazy. Give her to God and keep praying.
