Its not about religion. Its about relationship
In that case would it be reasonable for me to say that my girlfriend is God? I have a relationship with her. She has mysterious feminine wiles which I am at a loss to explain. She can control my behaviour (i.e. stop me from smoking and drinking too much). Even better than god, I can actually talk to her, and everybody else can see her. I just know that she's there. She imparts love to me and seems to know me even better than myself. I also fear her.
