I'd choose to work with God through his anger management issues. Perhaps he has had some emotional trauma in his past that is responsible for his current state. Maybe his father was neglectful and his mother was a manna-holic. It is clear that if he existed, he would be a deeply disturbed being, and would need to be treated with care. Not unlike a small child or a mental patient. With enough time and effort on humanity's part, the healing of this addled deity could finally begin.
"Faith is about taking a comforting, childlike view of a disturbing and complicated world." ~ Edward Current
