If you are going to say God is sending messages to Physical Human Beings then you can't exclude Physical Science out of it. Because both use the exact, same Physical Universe!
There may be a coexistance of physics and methaphysics. Human beings could be both, part of them is physical part of them is mp. Your soul, for example. Then God could communicate with your mp part.
Another possibility is that physics is just the part of the world that we know. And metaphysics is the part we know + all the rest.
