I went over a lot of this some pages ago. The metaphysical, by virtue of being metaphysical, is something whose properties we can't comprehend. We can know that a metaphysical things "exists" but we cannot know in what way it exists. We can't know whether or not it is good or evil, one or two, big or small, omnipotent, immaterial, or any other adjective that we typically use to describe physical, observable things. As entities of the natural world, we can only understand things by relating them to natural concepts, but a metaphysical thing may not, and likely is not, subject to any of the natural concepts that we can understand. Therefore the question of the qualities of the metaphysical "god" is invalid, in fact, the entire notion of their being "qualities" to a "god" at all is invalid because we have no way of knowing whether we can understand that metaphysical entity in this way. We can only know what we can conclude from necessity: that it exists and that it created (at least) the most basic entity of our natural existence (energy, the big bang, or whatever).
