We can tell from this that in its literal meaning the Word is really the Word. There is spirit and life within; the spiritual meaning is its spirit and the heavenly meaning is its life. This is what the Lord said: “the words that I speak to you are spirit and are life” (John 6:63). The Lord said his words to the world and said them in their earthly meaning.
Apart from the earthly meaning, which is the literal meaning, the spiritual and heavenly meanings are not the Word; [without it] they are like a spirit and life without a body–and as just noted in Section 33, like a palace that has no foundation to rest on.
