By faith, Abraham lived in tents because “he was looking for the city which has foundations, whose architect and builder is God” (Heb. 11:10). It is the Apostle John who gives a picture of the city that Abraham sought. It is indeed a city with foundations—massive foundations.
If the dimensions were literal, the City of God is 12,000 furlongs by 12,000 furlongs or 1500 miles wide and 1500 miles deep. That’s 2 million 250 thousand square miles. I take the measurement of its height to mean that it is a city set on a hill, a mountain fortress that is 1500 miles high. It’s surrounded by walls 72 yards or over 20 stories tall.
Again, if the dimensions were literal the heavenly Jerusalem is a city over 270 times higher than Mt. Everest and covering 8.5 times more territory than Texas. But mind you, this is not a state, not a country, not a continent—this is a city.
The Lord wants us to understand the magnitude, the reality, the concreteness of this city. We tend to think of heaven, its surroundings, and its citizens as floating in clouds in a kind of ghostly existence. Heaven is real. More real than anything you’ve ever experienced. It is denser. It is larger. It is higher. It is wider. It is richer. It is brighter. It is fuller. We live presently in the land of shadows. But this is the real city. A city with real foundations that are never shaken.
