Well said, very similar to St. Thomas Aquinas line of reasoning on the primary mover. I will say what you said in a slightly different manner. We live in a natural world...a physical world. God, resides in the supernatural, non physical existence.
It's physical enough. Although the Father is Spirit, Jesus seated "next" to Him has His glorified body, as will we.
One of the interesting questions I wish to have God answer--and which I wonder if then I'll still desire it--is the full rationale for why God wanted us to have physical bodies while He solved the problem of evil, and also why we'll have the new, improved versions in His new creation. So many questions...
