There's a few YouTube formats for Rabbi Cahn's presentation; a long lecture from a podium, and several interview shows. This is the best in my view; short, clear, and you can fast forward through the promo's.
The book is formed as a novel, and is a readable quick read. Some passages to get the flavor of it.
No other nation had been called into being for the will of God… No other people had been given a covenant… If (
) followed the ways of God, they would become the most blessed of nations. But if they fell away and turned against His ways, then their blessings would be removed and replaced by calamity, as they did and as it was. (pg. 16) Israel
To be…an instrument of God’s purposes, a light to the world. It would give refuge to the world’s poor and needy, and hope to its oppressed. It would stand against tyranny….As much as it fulfilled its calling or aspired to, it would become the most blessed, the most prosperous, the most powerful and the most revered nation on the earth-just as its founders had prophesied…but, like Israel, if the people fell away from God and turned against his ways, its blessings would be removed and replaced with curses.(pg19)
"As God was expunged from American life, idols came in to fill the void-idols of sensuality, idols of greed, of money, success, comfort, materialism, pleasure, sexual immorality, self-worship, self-obsession. The sacred increasingly disappeared, and the profane took its place….the nation forgot its foundations"
“Yes. The same tolerance that overtook ancient
.. a tolerance for everything opposed to God….a tolerance that mocked, marginalized, and condemned those who remained faithful to the values now being discarded…. A tolerance that put the profane on public display and removed nativity scenes from public sight..contraband, as if somehow they had become a threat- a strangely intolerant tolerance.” (pg. 21) Israel
My view for some time, is our nation, by turning away from God, like ancient Israel had, is leading us to our end as the most free, most materially and religiously successful nation in history. This bears it out.
