Nicole, what a blessing that you found a relationship with Jesus at such a young age. I believe the adversities you are facing with your family will make you stronger in the Lord.
Just love your father. Children can never realize how much a parent has been hurt because we parents try to hide it from them. Many of us are successful at it. Know that beneath the layers that you see your dad is in pain from his life. Just love him. He will see Jesus in you, and that will guide him back to the One who loves him.
