This work, originally published in 1766, unfolds the spiritual meaning of the Book of Revelation. It shows that by the "Seven Churches in Asia," to whom this prophecy is addressed, are meant the different classes of Christians of the present day; that the Last Judgment is not an event that is to occur at some future time in the natural world, but one that has already taken place in the world of spirits, and that " the New Jerusalem coming down like a bride out of heaven," symbolizes a new dispensation of truth now descending into the minds of men. Incidentally it explains numerous passages from other parts of the Word. Instructive narratives of things seen in the spiritual world are also interspersed between the chapters.
