'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

4041. The heavenly form is amazing, completely surpassing all human intelligence, for it is far beyond and above the ideas of forms which anyone can possibly gain from worldly things, even with the help of analytical arguments. In accordance with this form all the heavenly communities are arranged in their proper order; and what is remarkable, a rotatory movement involving those forms is taking place - a movement of which angels and spirits do not have any actual sensation. It is like the progress of the earth, spinning daily on its axis and orbiting yearly around the sun, which is not perceptible to its inhabitants. I have been shown the nature of the heavenly form as it exists in the lowest sphere. It was like the form taken by the sinuous curvings which are visible in the human brain. This curving round or sinuous overlapping I was allowed to observe clearly, and to do so for several days. From this I was able to be shown that the brain has been formed in accordance with the flowing movement belonging to heaven. But the interior parts of it which are not visible to the eye accord with the interior forms of heaven, which are quite beyond comprehension. I was also told by angels that from this one can see that the human being has been created according to the forms which the three heavens take, and that in this way the image of heaven has been imprinted on him, so much so that the human being is in form a very small-scale heaven and that this is the origin of his correspondence with the heavens.
