Anthropomorphic God and Nature

In the last class we discussed how Hume gave "Nature" a voice, and an anthropomorphic view. It was said that this action was done to emphasize and to capture readers and possibly for readers to understand it better.

Is it not the same about God? Throughout elementary school I grew up thinking about God being this old man "in sandals" . Maybe this was so a child around the ages of 5-12 could better understand. In fact in many psychology studies, children at the age are not capable of thinking completely abstractly. In this sense, this "concrete"(Piaget) anthropomorphic image is given to God for these young children to understand. It is biologically not possible for someone of such a young age to think abstractly. It does not deal with just God, but also the universe.

Is labeling God as this "old man" similar to what Hume does with Nature? They both are trying to reach the reader but why would this be any different? (because it has to deal with God or any higher power and you can never equate the two.... why??)
