Jerusalem
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.

It is well known that one person is endowed with a greater ability than another to understand and perceive what it is to behave honourably in private life, to be upright in public life, and to seek what is good in one's spiritual life. The reason why he has that greater ability lies in the fact that his thought has been raised towards the things of heaven and is consequently drawn away from the level of the external senses. For people whose thought does not rise above the level of the senses cannot begin to see what is honourable, upright, or good. They therefore rely on what others think, and base most of what they say on matters stored in the memory, and in doing this seem to themselves to be wiser than others. But those who can think on a level above the senses possess, if the contents of their memory are all in order, a greater ability than others to understand and perceive. Their ability depends on the height of the interior standpoint from which they look at things.
