'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.

116. THE SUN IN HEAVEN.

In heaven neither the sun of the world, nor anything from that sun, is seen, because it is wholly natural. For nature has its beginning from that sun, and whatever is produced by means of it is called natural. But the spiritual, to which heaven belongs, is above nature and wholly distinct from what is natural; and there is no communication between the two except by correspondences. What the distinction between them is may be understood from what has been already said about degrees (38), and what the communication is from what has been said in the two preceding chapters about correspondences.
