Anyone with some knowledge about the new testament ?

[Mr Quatro]

the term “Israel” is used a total of 73 times in the New Testament

but the term Israel and the name of Jerusalem are used many times in the old testament to mean the same thing.

For instance the New Testament in The Book of Revelations talks about at the end of the 1,000 years of peace that a New Jerusalem shall come down out of heaven ...
which leads to a whole lot of other questions like what comes down might go back up.

So what's you real question Markus all of the above came from a simple search by the way
