Laidlaw college has recently hosted a dialogue/debate on the the subject and kindly provided the videos,
This is Richard Neville, who argues the Bible teaches that the nation of Israel will be restored, he focuses on Ezekiel and a little on the NT understanding.
And this is Stephen Sizer, who argues against Christian Zionism and for a more inclusive understanding of the who "god's people" are. He starts off by focusing on the Left Behind video game, but does get to the Bible soon enough.
Let me know what you think. :-)
