Teaching my children about Faith

I grew up a Christian, and I married a Christian, but he was unfaithful and we separated as a result. We have three children, 14, 12, and 9. They were raised Christian in the church, which was Apostolic, however, we moved due to the military and their father became transgender, and our oldest has fallen further away from Christianity because she feels that the church condemns her father and she doesn’t want to have much to do with it Christianity anymore. Her grandmother became hateful toward her father after he came out publicly as a transgender. And now she’s pulled away from Christianity because she only sees the hate it’s caused towards her dad. I can tell she’s still a believer, and she will sing to gospel music like Lauren Daigle when I play it, so I know it’s still there in her heart.

The kids also made friends in school prior to getting homeschooled, and those friends are liberal and they are against the church and having faith. Now, I am by no means religious, but I’ve always had a relationship with God and I have a lot of Faith.

My question is: With regard to my oldest, primarily, how can I lead through Faith and make her feel that she doesn’t have to follow her friends? That she can keep her Faith and still love her father. It’s been so hard for all of the kids, but she’s taken it the hardest. I don’t want to be controlling, and I want her to have the choice, but I want her to feel confident in having a relationship with God.
