The occurrence of written materials in the heavens is provided by the Lord for the sake of the Word, for in its essence the Word is the divine truth from which both angels and people on earth get all their wisdom. It has in fact been spoken by the Lord, and what is spoken by the Lord passes through all the heavens in sequence and comes to rest with us. In this way it is adapted both to the wisdom that angels enjoy and to the intelligence that we do. As a result, angels have a Word that they read just as much as we do ours. They draw their doctrinal principles from it, and their sermons come from it (Section 221).
It is the same Word; but its natural meaning, which to us is its literal meaning, does not exist in heaven. There is a spiritual meaning there instead, which is its inner meaning. The nature of this meaning may be seen in the booklet The White Horse Described in the Book of Revelation.
