Gold means good, and just as gold was the most precious metal known to ancient mankind so it represents the good of the highest and wisest of the angels. These angels foremostly love the Lord, and because they do they act from that love at all times. So the things they do are from love or as the writings for the new church often say, their acts are "goods of love". This is what gold represents. As soon as God planted the garden of Eden, He created a river in it, to water it. This river went out and branched into four, the first branch mentioned, Pishon, encompassed the "…land of Havilah, where there is gold… and the gold…is good". Another mention of gold comes in Exodus where the Lord is telling Moses how to make the Tabernacle. If you pay attention you will see that inside the tabernacle the main thing you see is gold, the boards of the wall are covered with it and all the furniture is either wood covered completely with gold, or is made of solid gold. Then at the end of the Word the holy city descends from God and it is made of gold, "gold like unto clear glass" good of love that can be clearly and completely understood. And it has its river. This is a promise from the Lord that we can come into a state similar to that of the garden of Eden, if we follow Him so as to come into love for Him, and act from that love.

Generally, doors in the Bible represent the initial desires for good and concepts of truth that introduce us to new levels of love and understanding, and even to the Lord Himself. Since a “house” represents a person’s desires, affections and passions, the door serves to introduce true ideas that can put those desires into action.

In John 10:7, the door signifies the Lord, who is good itself and truth itself. (Arcana Coelestia 2356[2])

In Revelation 3:8; 4:1, the door signifies admission to the arcana of heaven revealed. (Apocalypse Explained 260[2])

The meaning depends on context, of course. For example, references to doorposts and lintels are making a distinction between introductory goods and introductory truths. And, in Sodom, Lot's house had two doors -- an inner one and an outer one. When, in Genesis 19:6, Lot tried to convince the men of Sodom not to attack the angels visiting him, he went outside the inner door, but stayed inside the outer door. There, the outer door represents a desire for good that is resistant to the falsity represented by the men of Sodom; the inner door represents true ideas springing from that desire for good. Someone nurturing a desire for good could be admitted through the first door, but would have to learn the truth about how to express that desire before being admitted through the second.
