Jerusalem, on Mount Zion, signifies the doctrine of love to the Lord, and how it governs your life. Jerusalem first comes to our attention in 2 Samuel 5, when King David takes the city from the Jebusites and makes it his capital. In the next chapter he brings the Ark of the Covenant there, and later it is where Solomon builds the temple, and his own palace. From then on Jerusalem is the center of worship of the Israelitish church. It is the place where the Lord was presented in the temple as a baby, where He tarried to talk to the priests at age twelve, where He cleansed the temple, had the last supper, was crucified and then rose. It is a central place in both the old and new Testaments. The city was built on Mount Zion, the highest point of the mountains of Judea. A city, in the Word, represents doctrine, the organized knowledge of the truths of the church. Mountains represent love of the Lord and the consequent worship. If you put those things together, Jerusalem on Mount Zion signifies the doctrine of love to the Lord, and how it governs your life. This is why David was led to make Jerusalem the most important city of the land, and why all worship was conducted there. And this is also why Jeroboam was condemned for introducing idol worship in Samaria. In the Book of Revelation, John's vision of the city New Jerusalem descending from God is a prophecy of a new dispensation of doctrine coming from the Lord.

345. And the honor and the glory, signifies that to Him alone belongs every Divine good and Divine truth, and therefore every good of love and truth of faith that angels and men have. This is evident from the signification of "honor and glory," as being, when said of the Lord, Divine good and Divine truth (See also above, n. 288. And as "honor and glory" signify, when said of the Lord, Divine good and Divine truth, so when said of man they signify every good of love and truth of faith, from which are all the wisdom and intelligence that angels and men have. These things were said by those who are in the lowest parts of heaven, who know this, although they do not see and perceive it. For all who are of the church know, because it is according to doctrine, that every good and truth is from God; and those who live a good life retain and believe this without investigating how it comes; for this reason these also are in heaven, although in its lowest part. But those who have become spiritual not only know but also see and perceive that this is so; consequently these are in the higher heavens. When such come into the spiritual world they see truths and perceive them in the light of heaven; nor do they admit the rule accepted by many in the world, that the understanding must be under some blind obedience to faith. With those who are in the lowest parts of heaven it is otherwise, because they do not see and perceive; these remain in that rule, but still they are instructed, and when instructed they know truths.
