As far as I'm concerned, that would make you a theist.
I believe that our concept of justice is something God designed into us, in order to be able to make laws. I do not believe that it matters to God, I think He is beyond that.
That would be a more Buddhist view, I think. So why does God want us to make laws, do you think?
Possibly to make it possible for societies to form and to distinguish us from animals?
