One mountain is the old covenant mountain and the other is the new covenant. The old covenant has another name? What is it?
Now let’s read our second “to”. It is the heavenly Jerusalem, the city of the living God. God design and built this heavenly city for us on top of a mountain called Mt. Zion. This is our hometown as we will see later. We are entering the holy city.
The same mountain and the city will all come down to a new planet earth. In the future, heaven will down to earth.
Notice Revelation 21:9-12. The great and high mountain, which is Mt. Zion and the Holy City, will come down from heaven but right now they are still in heaven.
