Well, in reply there is a lot of things I might say, one being, though you may not be a “flaming” liberal, you must be some sort of liberal, I refer to your belief of a one world government...and your seeking to enlist Jesus for that cause. That’s the cause of the liberals, the socialists and democrats, not conservatives.
As to Jesus’ prayer, you may not realize people do this, but they tend to read into scripture their preconceived notions. I don’t believe Jesus was praying for a collectivist one world utopia at all. That has to be read into the text.
To rightly exegete John 17, one must factor in many things. For instance, was Jesus an Amillennialist? praying for a one world religion under the Pope (according to Roman Catholics)? The larger context says no (the body of prophetic scripture).
You mentioned context, the larger context is not just John 17, the millennial kingdom, just one item in that context.
‘you must be some sort of liberal’
No need to read further. When you get something this basic wrong, the likelihood is that you’re wrong about everything else too.
