Use my hate ?

My brother and I were adopted by an American family from a Russian orphange as young
kids. We are now teenagers.
I heard you on the radio and begged for your book.
I have hurt my American parents so much with my anger, rebelliousness and hate.
I knew in my heart that God could NEVER use me, but when I read your book, you
brought me hope for a better live and that God can even use people like me, or as you
say: kids like us.
Please know, that you have truly changed my life. Thank you so much.
