God could be all knowing, all powerful and loving in its own terms if you imagine it being some sort of programmer who created this software for simulating us. He (or whichever gender) could be all knowing in the sense that at any given moment he can check the state of the system and all powerful that he can tweak the state or save/load, and loving in the sense that he totally loves the system he built. It keeps him entertained for years. And he's not even a psychopath, because he thinks it's all just code, and he's otherwise a kind person irl.
