How Many Christians Are There?


I have a question relating to the reported size of the New Kingdom or new earth that the Church will inhabit. You stated that it will be 1400 miles tall and wide. The way I see it is that it is not very big. Perhaps close to 1/8 the size of the earth? But from other descriptions there is also supposed to be plenty of room for everyone.

I guess what I am getting at is that it seems to me that this all appears to look like there won’t be all that many people that make it there. Are there really that few born again Christians in the world?

Also, where does this measure come from? I ask this question only because when I tell people this they question where this is found in the Bible. You and your website have been such a blessing-solid-honest- everything I have looked for to go along with my own studies. Thank you and may God Bless You for your efforts.


If it was located on Earth, the New Jerusalem would cover all of western Europe from Scandinavia to Italy, or all of the eastern US from the Atlantic to the Mississippi River. The tallest building on Earth is about 1800 feet tall. The new Jerusalem is 4000 times taller.

The Earth has a diameter of 8,000 miles. The New Jerusalem, at 1400 miles, is not quite 1/5 the size. The reference is Rev. 21:16 where its dimensions are given as 12,000 stadia in length and as wide and high as it is long. 12,000 stadia is 2,200 kilometers or about 1,400 miles.

But since 70% of the earth’s surface is water, and a large portion of the land is uninhabitable, there may actually be more usable space in New Jerusalem than on Earth.

No one knows how many born again Christians there are, but it’s estimated that there were 300 million people alive on earth when Jesus was born. Today there are 6 billion. That means that Earth’s population has doubled 4.25 times since then. If only a small percentage of the people born in the last 2000 years became believers, the New Jerusalem could become home to a billion people or so.
