Correspondence, though, extends to much more than human beings. There is a correspondence of the heavens with each other. The second or intermediate heaven is responsive to the third or central one, the first or outmost heaven is responsive to the second or intermediate one, and this is responsive to the physical forms in us, the forms that are referred to as our members, organs, and viscera. So it is our bodily nature in which heaven finally comes to rest, on which it stands like a foundation. But this mystery will be explored further elsewhere.
It is absolutely necessary to realize, though, that all correspondence with heaven is correspondence with the Lord’s divine human, because heaven is from him and because he is heaven, as has been explained in the preceding chapters. For unless the divine human flowed into every bit of heaven and, in accord with correspondences, into every bit of our world, there would be no angels and none of us.
Again then, we can see from this why the Lord became an individual on earth and clothed his divine nature with a human nature from first to last. This happened because the divine human on which heaven depended before the Coming of the Lord was no longer adequate to sustain everything, since we, the foundation of heaven, had undermined and destroyed the design.
In the passages referred to at the close of the preceding chapter you may see what the divine human before the Coming of the Lord was and what its nature was, as well as the quality of the state of heaven then.
