919. 21:23 The city had no need of the sun or of the moon to shine in it, for the glory of God illuminated it, and the Lamb is its lamp. This symbolically means that people of the New Church will not be caught up in self-love and their own intelligence and so possess a natural sight only, but from the Word's Divine truth will possess a spiritual light from the Lord alone.

The sun here symbolizes natural love divorced from spiritual love, which is self-love. And the moon symbolizes a natural intelligence and faith divorced from a spiritual intelligence and faith, which is one's native intelligence and a self-made faith. This is the love and the intelligence and faith symbolized by the sun and moon here, which people of the Lord's New Church will have no need of to light their sight.

The glory of God which illumines the city symbolizes the Word's Divine truth (no. 629), and because that illumination or enlightenment comes from the Lord, we are told as well that the Lamb is its lamp.

The symbolism here is similar to that found in the following verses in Isaiah:

You shall call your walls salvation, and your gates praise. The sun shall no longer be your light by day, nor for brightness shall the moon give light to you; but Jehovah will be to you an everlasting light, and your God your glory. Your sun shall no longer go down, nor shall your moon wane; for Jehovah will be your everlasting light... Your people shall all be righteous. (Isaiah 60:18-21)

The sun and moon that will no longer give light mean self-love and one's native intelligence. And the sun and moon that will no longer go down mean love from the Lord for the Lord, and an intelligence and faith from Him. That Jehovah will be an everlasting light has the same symbolic meaning as what is said here, that the glory of God will illumine the city and the Lamb be its lamp.

That the sun symbolizes love for the Lord, and in an opposite sense self-love, may be seen in nos. 53 and 414 above. And that the moon symbolizes intelligence from the Lord and faith from Him, in nos. 332, 413, 414. Thus the moon in an opposite sense symbolizes one's native intelligence and a self-made faith.

Since the sun in an opposite sense symbolizes self-love, and the moon one's native intelligence and a self-made faith, therefore it was an abomination to worship the sun, moon and stars, as may be seen in Jeremiah 8:1-2.

'A temple' represents heaven and the church. The sacred place where the ark was, represents the inmost, or third heaven, and the church among people in the inmost principle, called the celestial church. The temple outside the sacred place represents the middle, or second heaven, and the church with people in similar principles, called the internal spiritual church. The inner court represents the outermost or first heaven, also the church with people in outer degrees, called the internal natural church. The outer court represents entrance into heaven.

'Temple,' as in Revelation 15:8, signifies divine truth, or the Word in the natural sense, in light and power from the divine truth in the spiritual sense.

'I saw no temple in it,' as in Revelation 21:22, does not mean that in the new church, which is New Jerusalem, there will be no temple, but that externals will not be separated from internals. This is because 'a temple' signifies the church regarding worship, and in the highest sense, the Lord Himself regarding the divine humanity, who should be worshiped. Because the whole church is from the Lord, it says, 'for the Lord God Omnipotent and the Lamb is the temple thereof,' which signifies the Lord in His divine humanity.

'Temple,' as in Luke 21:5-7, signifies the church at this day, in which there is no truth left remaining, and as a result, is at an end.

'Temple' signifies the higher heavens.

'Temple' signifies the Lord's divine human with respect to divine truth.

'The temple of His body,' as in John 2:21, signifies the divine truth from the divine good.
