It follows from all this that without its literal meaning the Word would be like a palace without a foundation, like a castle in the air. The only thing on the ground would be its shadow, and shadows disappear. The Word without its literal meaning would be like a temple containing an abundance of holy objects, with a central inner sanctum, but without a roof or walls to contain them. If these were lacking or were taken away, its holy contents would be plundered by thieves or torn apart by the beasts of the earth and the birds of heaven, and would therefore be scattered far and wide.
By the same token, it would be like the tabernacle’s inmost area, which housed the ark of the covenant, and its middle area, which housed the golden lampstand, the golden altar of incense, and the table with the showbread on it—all its holy contents—without the curtains and veils that surrounded them.
The Word without its literal meaning would be like a human body without the coverings called layers of skin and without the structural supports called bones. Lacking both of these, all the internal organs would spill out.
Then too, it would be like the heart and lungs in the chest without the covering called the pleura and the framework called the rib cage, or like the brain without its specific covering called the dura mater or its general covering, container, and support called the skull. That is what the Word would be like without its literal meaning, which is why it says in Isaiah that Jehovah creates a covering over all glory (Isaiah 4:5).
It would be the same for the heavens where angels live if it were not for the world where we live. We, as human beings, are their foundation, container, and support, and we have the Word with us and in us. Overall, the heavens are divided into two kingdoms, which are called the heavenly kingdom and the spiritual kingdom. These two kingdoms are founded upon the earthly kingdom where we live. A similar structure exists in the Word, which we have with us and in us.
