Apocalypse Explained #528
528. Verse 13. And I beheld, and I heard one angel flying in the midst of heaven, saying with a great voice, Woe, woe, woe, to them that dwell on the earth, by reason of the other voices of the trumpet of the three angels which are about to sound!- "And I beheld, and I heard one angel flying in the midst of heaven," signifies the Lord enlightening all in the heavens concerning the state of the church at its end; "saying with a great voice," signifies in manifestation; "Woe, woe, woe, to them that dwell on the earth by reason of the other voices of the trumpet of the three angels which are about to sound," signifies grievous lamentation over the changes of the state of the church, on account of the turning away from good and truth, and thence damnation.
Heaven and Hell #116
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.
