13 is pretty old for a dad to dictate to a kid what their beliefs should be if he hasn’t been doing it well from the start. The kid may just stand up to s judge at some point and say...you crazy judges have been supporting under age kids rights to change their gender, never mind what their parents want, but they are then going to say I have to accept my father’s dictates as to my chosen religious beliefs should be?
It sounds like the dad is being boxed into a spiritual corner by God himself and he is fighting viciously against it!
What will the dad do to the daughter if she continues to pray for his soul anyway?
