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.

9682. 'And you shall put the mercy-seat onto the ark of the Testimony in the holy of holies' means the hearing and reception of all things which in the inmost heaven belong to worship arising from the good of love from the Lord. This is clear from the meaning of 'the mercy-seat' as the hearing and reception of all things that belong to worship arising from the good of love, dealt with in 9506; from the meaning of 'the ark of the Testimony' as the inmost heaven where the Lord is, dealt with in 9485, 'the Testimony' there being the Lord, 9503; and from the meaning of 'the holy of holies' as the place where the good of love from the Lord dwells, dealt with above in 9680. From all these meanings it is evident that 'you shall put the mercy-seat onto the ark of the Testimony in the holy of holies' means the hearing and reception of all things which in the inmost heaven belong to worship arising from the good of love from the Lord.

[2] The nature of the Lord's presence in the inmost heaven, and the nature of His presence in the middle heaven, and also in the lowest, may be recognized from what has been shown in many places regarding the inflow of goodness and truth from the Lord. The Lord becomes present by flowing in, but this inflow is conditioned by what people's life of goodness and truth is like. Those governed by the good of love to the Lord are the ones to receive that inflow the most immediately. Those however who are governed by the good of charity towards the neighbour receive it as well, yet more remotely, because the good of charity towards the neighbour is more remote than the actual good of love to the Lord. As for those who are governed by the good of faith, they too indeed receive it, but according to the amount of good there is within that faith. Consequently people who lead a good life based on the truths of faith receive it; for the Lord resides within their good, since all good springs from Him and none whatever from man, nor from the angels in heaven.

[3] To pursue this matter further, that the Lord is present in heaven and with mankind through heaven, it should be remembered that the Lord is above the heavens, since He is the actual Sun of heaven; yet He is nevertheless present in heaven through the light and heat from that Sun. The light from it is the Divine Truth which is the light of faith, while the heat from it is the Divine Good which is the heat of love; what emanates from the Lord is the Lord Himself. From these considerations it is evident that the Lord is present where good received from Him dwells. But a better understanding of all this may be gained from what has been shown regarding influx, that is to say, where it has been shown that the all of life, thus all good and truth since these constitute life in a person, flows in from the Lord, and that the things which flow in are conditioned by the manner in which each person receives them, 2536, 2706, 2886-2889, 2893, 3001, 3318, 3484, 3742, 3743, 4151, 5846, 5850, 5986, 6053-6058, 6189-6215, 6307-6327, 6466-6495, 6598-6626, 6982, 6985, 6996, 7004, 7055, 7056, 7058, 7147, 7270, 7343, 8321, 8685, 8701, 8717, 8728, 9110, 9111, 9216, and where it has been shown that influx from the Lord comes both directly from Him and also indirectly through the heavens, 5147, 6058, 6063, 6466, 6472, 6473, 6982, 6985, 6996, 7004, 7007, 7055, 7056, 7058, 7270, 8685, 8701, 8717, 8728, 9216.
