The relationship between parent and child is first formed on the physical level. god doesn't show up on the physical level, so we cannot develop this kind of connection with him.
If he was really interested in developing this kind of bond with the rest of us, he would physically be there with us from the beginning.
It's like trying to develop a relationship with a parent, when you never see or hear from that parent, and all communication is through written letters or email.
You can still love someone through letters or email.
