When Writing About the New Earth, Did You Mean to Leave out the New Jerusalem, which Is the Final Heaven, and Is Described in Rev. 21 and 22?
The point is where the New Jerusalem is located. It is brought down to the New Earth and is the capital city of the New Earth. When I talk about the New Earth I am including the New Jerusalem. However, the New Jerusalem does not include the whole New Earth. For example, when you speak of Oregon, does that include the city of Portland? Yes. But if you speak of Portland, that doesn't include the whole state of Oregon.
Scripture speaks of the New Earth in certain places (II Peter 3:13, Isaiah 65 & 66) without mentioning the New Jerusalem. These scriptures all use the term New Earth without using the term New Jerusalem.
