1. God punishes Man for Sin. So Israel gets what it deserves. So maybe Auschwitz is god slapping back for rejecting Jesus. And maybe the Autistic and all the Harelips are working off Karma. Maybe god kills babies because they used to be Himmler. But then, Job was not guilty of any sin - that's why Yahweh took the bet with Lucifero - Job was a lock. It was a boat race. God always knew how the outcome would unfold.
2. It's the Devil. He's responsible for our misery and sins. Oh oh, the whole bidnez of Yahweh is Monotheism. There is, he keeps screaming, only one god. And Man has Freedom of Choice - that's a given, or it's all just a fucking Ant Farm and we're too stoned to see the plexiglass boundaries in our reality. So even if there Was an evil 2nd god - he couldn't make you do anything. Nietzsche may hear the ramblings of Zarathustra but Manicheism & Dualism are intellectually bankrupt ideas.
3. "It's all good." We just don't see the big picture. God needs us to suffer and bleed and go bug-fuckin' nuts for reasons too sublime for our puny little Mirror Neurons to reflect. St. Paul was big on this answer. Leprosy is actually some kinda hidden blessing. Yah, that's it. Nagasaki, from god's perch, was a creme-brulée. This answer has been filling Mental Institutions for a long time.
4. There is no god. Or, if there is, it does not concern itself with the running of the worlds. This is Modernity and Existentialism. It's all just an accident, and since in a world where everything happens by chance there is no meaning to a word like accident - then it must be Zen, a "happy accident."
5. God is half-baked. "God is an antinomy who isn't quite conscious of what he is doing." This, Fast Eddy reminds us, is Jung's answer. Man creates god in his own Image and Likeness and if Man is not fully conscious then the God he creates must Mirror that circumstance. The Jews, at the time of the Book of Job, projected the Face of God which fit their own Face. Job knows this about god and his gnosis changes both himself and his projection, god. So god needs us just as much as we need god.
