The 'sun' in the Word, when referring to the Lord, signifies His divine love and wisdom. Because the sun represents the Lord, with respect to His divine love wisdom, since ancient times even to the present day, worship is done and temples are built facing the rising sun. The sun signifies celestial and spiritual love and also the Lord regarding His divine love, and so the good of love from Him. In the opposite sense, it signifies a denial of the Lord's divinity, and so adulteration of the good of love.

In Genesis 15:12, 19:23, this signifies the time and state before consummation; for the sun signifies the Lord, and the celestial things of love and charity; so its setting represents the last time of the church. Its rising signifies a coming of the Lord, and the first period of a new church. (Arcana Coelestia 1837, 1859)

In Jeremiah 8:1, this signifies self-love and its lusts. (Arcana Coelestia 2441)

In Revelation 12:1, this signifies love. (Arcana Coelestia 253, Arcana Coelestia 3272[2])

Sun signifies the good of love. (Arcana Coelestia 4918[3]）

(Odkazy: Apocalypse Explained 709)

709. And upon her head a crown of twelve stars, signifies the wisdom and intelligence of those who are of that church through doctrinals and knowledges of all things of truth and good from the Word. This is evident from the signification of "head," as being wisdom and intelligence (of which above, n. 553, 577), here of those who are of the church that is signified by "the woman arrayed with the sun, and the moon under her feet;" also from the signification of "crown," which also means wisdom and intelligence (of which above, n. 126, 218, 272), also from the signification of "stars," as being the doctrinals and knowledges of truth and good from the Word (of which see n. 72, 402, 535), also from the signification of "twelve," which means all, and is predicated of truths and goods (See n. 430). From this it is clear that "the crown of twelve stars upon the head" of the woman signifies the wisdom and intelligence of those who are of that church through the doctrinals and knowledges of all things of truth and good from the Word. This is said of the woman after it is said that she was "arrayed with the sun, and the moon was under her feet," because the "sun" signifies celestial and spiritual love, and the "moon" the faith of charity, and from these all wisdom and intelligence flow forth; for from the Lord as a sun heat and light proceed, and heat is the good of love, and light is truth from that good, and these two constitute wisdom and intelligence with angels and men, for the good of love enters their will, and truth from that good enters their understanding, and in the will and understanding together wisdom has its seat.
