He helps believers with trivial problems in their lives, like money, success, long life etc while expecting human beings to stop all the wars, famines, and genocides, even though he's got infinite power and could do it instantly
Seriously, he has his followers on Earth raising money, and spreading the word for him.
He has women creating more humans.
He doesnt intervene in any wars or acts of genocide.
What does he do all day? Just sit back and watch the chaos?
Interestingly enough, I've heard many a Christian say that "the Devil's always busy."
And if there truly is a Devil, I believe he is quite busy. Evidence of his mayhem can be seen around the world.
It would be cool if God made some new animals, at least.
