Napsal(a) Joe David
Jerusalem first comes to or attention in II Samuel, chapter 5 where King David takes it 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 of Jerusalem 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. Jersualem 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, some of which you may read in the references list below.
