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]）

252. The woman' is used to mean the Church. This becomes clear from the heavenly marriage, dealt with above in 155. The heavenly marriage is one in which heaven, and so the Church, is united to the Lord by means of the proprium, even to the extent of it existing within the proprium itself; for if there is no proprium the union does not exist. And when the Lord from His mercy instills into this proprium innocence, peace, and good, it still looks like the proprium, but it is now something heavenly and richly blessed; see what has been said already in 164. But the nature of the heavenly and angelic proprium obtained from the Lord on the one hand, and the nature of the hellish and devilish proprium deriving from self on the other, defies description. The difference is like that between heaven and hell.
