I really enjoyed this book, and right after I started reading it I noticed two other authors I respected had also recently made mention of it, so I figured it should be a good read. The issue of Zionism, or those who feel Israel deserves to be back in their land due to some biblical, covenantal, or eschatological reason, really need to examine the issue further; and this book is a great place to start.
I was thinking it was going to just be a book to counter the many modern arguments in support of modern Israel, but instead it is a fairly thorough historical march through the Bible, covering the covenant, the promises, and the importance of the land along the way. Most of the way through, it spoke so much in favor of the importance of the land, that I thought it was going down a path other than what I thought the intent was. Then as he approached the New Testament, and the new covenant, the shift began, and the last couple chapters examine the view of the land in those last days for the Christians.
Kenneth Gentry recently commented, saying this book is one of a few books that has greatly shaped his view of Israel and the land, and that after reading this and the couple others, if someone still could cling to a modern dispensational view of the land, then they are probably beyond hope (that is a paraphrase as I understood it).
Maybe this book had more of an excitement and impact on me due to it's heavy look into Israel's past and understanding of the land, since I had recently finished the Resurrection and the Restoration of Israel: The Ultimate Victory of the God of Life which examined a lot of historical understandings in Hebrew thought; but either way, this book was full of great content, history, and biblical conclusions. I have so many highlighted remarks throughout, it would be hard to narrow it down to give a brief synopsis, but I just encourage you to check this book out if you have any interest in the modern crisis in Israel over who has the rights to the land.
