When we think of a bride, we think of one woman. God uses the monogamous, desired relationship with a woman to describe His ability to have a relationship with all of His People as if they were one person. The New Jerusalem is a city, but it is also part of whom His Bride is. When God sees the House, he sees the Inhabitants.
The following verses describe the dimensions of its construction. At its base, the descending city is 2200 kilometers by 2200 kilometers. And then, it is 2200 kilometers high. It is described like a cube.
A metropolis of this size in the middle of the United States would stretch from Canada to Mexico and from the Appalachian Mountains to the California border. The New Jerusalem is all the square footage anyone could ask for… Given the dimensions of a 1,400-mile cube, if the city consisted of different levels, and if each story were a generous twelve feet high, the city could have over 600,000 stories. If they were on different levels, billions of people could occupy the New Jerusalem, with many square miles per person.[i]
Verse 17 says ‘The angel measured the wall using human measurement...’ This suggests that the description is literal. But, even if the measurements are symbolic they tell us that God is abundantly generous and capable beyond human comparison. If the Creator made the Universe, is it such a stretch that an enormous city would come from God’s hands?
The building materials of the city, the walls, the gates and the streets include many precious metals and jewels. Our greatest earthly palaces are humble outhouses compared to the gleaming glory of that City.
