Natural Law in the Spiritual World

Is there no reason to believe that many of the Laws of the Spiritual World, hitherto regarded as occupying an entirely separate province, are simply the Laws of the Natural World? Can we identify the Natural Laws, or any one of them, in the Spiritual sphere?
In "Natural Law in the Spiritual World" Henry Drummond deals with those questions by exploring the relation of religion and spirituality with the physical world. He argues that the disconnect between the spiritual and the physical was entirely illusory and that faith was by no means in conflict with science.
