In the ancient world, a deity wasn't neccessarily all-powerful. They also suffered from in-fight and jealousy and several other foul human traits.
What characterized the deities however, was that they were simply exaggerated versions of human traits, personalization of the human psyche.
I believe that the same thing happened to Judaism and later Christianity:
Yahwe, the god of the jews, wasn't alone. He competed with many other ancient gods. You can read that in the Old Testament: "You shall not have any other gods besides me". The word "other" indicates there was indeed more than one deity.
Yahwe won, but not all of a sudden. Yawhe won and became the sole deity of the jews, over many, many generations.
Eventually he became the master and creator of the universe and all-powerful as the writings progressed as does fan-fiction to this day. The Old Testament was no exception. It too was composed of many books, today we would call it fan-fiction or something similar, where the writings are written by the fans and developed and still develops. Like Harry Potter, Lord of the Rings etc.
Christianity broke with this tradition of a powerful deity - in a way we tend to forget.
In Christiniaty, Jesus (who is the son of God - or simply God) is not all-powerful. He isn't strong. He was weak. Not only that, the Christian God was portrayed as a weak, poor criminal who was executed for inciting rebellion.
Now, I don't believe Jesus was poor. I believe he was very well-educated and spoke fluid Greek, Aramaic and other ancient languages. Many of the sayings attributed to Jesus, shows signs of a well-scholared philosopher.
But try to think about the fact that he was actually a condemned criminal. And the fact that he died a horrible painful death (the resurrection story, was added much later, people tend to forget that too).
Now, why would anyone hold a criminal weakling as their deity?
The answer is firstly, although Jesus was a criminal, crime is simply breaking the law. And the Roman law was - lets face the facts: Injustice. I'm glad the Roman Empire is gone. If the law says "autistics should be executed for autism", it isn't the autistics who are the problem. It is the law.
Secondly even though Jesus was weak (and dead) the ethics Jesus taught are very valuable. We would be cruel barbarians if we didn't follow the ethics - at least partly - that Jesus taught. Not because Jesus taught them, but because this set of ethics are good for us - as humans, as society.
These include the ability to forgive, to love thy neighbor and taking care of those unable to take care of themselves.
I don't believe in the resurrection of Jesus. At least not the physical resurrection. And maybe Jesus didn't even exist but was simply a combination of many ancient philosophers woven into one. I don't know.
But I do know, if I should choose a deity hold dear, I certainly would NOT pick some kind of alpha-male pretending to be smart (Intelligent Design includes designing physical defects or nasty illnesses) then pretend to be blind and deaf as his followers pray to him.
I'd pick a loving, caring deity who wish me all the best - it would be nice if the deity could grant wishes, but it sure is better than the alpha-male-deity.
