Part of the complication of course is that the nation of Israel is sort of a precursor to the church.
In the beginning there was 1 nation.
Then there were many nations but one specifically chosen
Now there is 1 church that all become one in if they so choose to follow.
But we have things like
This certainly doesn’t make sense to some views of the end times. Judge what?1Co 6:2 Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters?
1Co 6:3 Know ye not that we shall judge angels? how much more things that pertain to this life?
The same time, why is one nation or another divided and is this a good thing or not? Should we cast out the foreigner ie John or is it fine to welcome him to our nation as us or our church as us?
If yes, then logic would dictate he is no different then any other who desires to join nation or church.
Perhaps we judge based on history? Australia was a prison colony. His people were rejected before, should we do the same?
