Men rarely (if ever) manage to dream up a god superior to themselves. Most gods have the manners
of a spoiled child
. --Robert Heinlein
Man created god. It shows.
In Norse mythology (and Greek, for that matter) the gods are petulant, bickering, in-fighting, and sneaky. Or, in other words, they lead a normal human family life.
In X-tianity, god is a sort of mega-father-figure. It's the ultimate voice that tells you what's right and what's wrong (and never tells you why, even though the 'bad' stuff is always the most fun...). He's mysterious, awe-inspiring, and more than a little scary. He is loved and feared in equal measure. What five year old doesn't think of their father in this same way?
It may help to understand human affairs to be clear that most of the great triumphs and tragedies of history are caused, not by people being fundamentally good or fundamentally bad, but by people being fundamentally people. --Terry Pratchett
We are people. We are human. Let's not try to deny or change that.
