He's basically stumbling through this whole god thing. Fresh into the position, he doesn't really know what he's doing—most situations just leave him at a loss. But here's the thing: he doesn't stress about it. At all. He just rolls with whatever happens and figures it out as he goes.
His whole personality is built on this carefree, almost cheeky attitude. He speaks without much of a filter, says what's on his mind, and doesn't take himself or the job too seriously. It's the kind of blasé confidence that either wins people over or makes them want to throw something at him.
