Heaven and Hell #172
172. But even though the things that are seen in the heavens are largely similar to things on earth, they are not alike in essence. The things that exist in the heavens come from heaven's sun, while earthly things come from our world's sun. Things that arise from heaven's sun are called spiritual, while things that arise from our world's sun are called natural.

240. VII. The Word is to be found in all the heavens and is the source of the angels' wisdom.
It has not previously been known that the Word is to be found in the heavens; nor could it be known so long as the church was unaware that angels and spirits are human beings, in face and body exactly like those in our world, and having surroundings in all respects exactly like those men have. The only difference is that they are spiritual and everything about them comes from a spiritual origin, while people in this world are natural and everything about them comes from a natural origin. So long as this fact remained hidden, no one could know that the Word is also to be found in the heavens and is read by the angels there, as well as by the spirits who are below the heavens. But to ensure that this should not remain a secret for ever, I have been allowed to enjoy the company of angels and spirits, talking with them, seeing their surroundings, and then reporting much of what I have seen and heard. I did this in the book entitled HEAVEN AND HELL (published in London in 1758). From this one can see that angels and spirits are human beings and that everything people in this world have is there in profusion for angels and spirits. It may be seen in that book that angels and spirits are human beings (73-77, 453-460); that they have similar surroundings to those people have in this world (170-190); also that they have Divine worship and sermons in their churches (221-227), also writings and books (258-264), and the Holy Scripture or the Word (259).
