That's a really good point, Jonathan. It highlights of course the absolutely impossibility of really nailing down anything definitive about God because of our severe limitations. How can ant explain a human? But, there is fun and value in using the rational capacities God gave us, as long as we don't put more on them than they can bear. We tend toward hubris for sure. I would say you are right in saying it is not beyond God to be both building and building, but then our ideas of distinctions, categories and ontologies break down at the mystery. I believe it is a simple and flawed analogy but if anything I would argue is that it succeeds better (rationally speaking!) than the mind-body analogy most used by panentheists.
