Really? What does Ezekiel say? "You will say, ‘I will go up against a land of unwalled villages; I will go to a peaceful people, who dwell safely, all of them dwelling without walls, and having neither bars nor gates’— to take plunder and to take booty, to stretch out your hand against the waste places that are again inhabited, and against a people gathered from the nations, who have acquired livestock and goods, who dwell in the midst of the land." (Eze 38:11-12). At the time of the Holocaust there was no nation of Israel: the places were wasted but the people had not yet been gathered from the nations. I'm not even sure it speaks of today, since Israel is not at peace or prosperous (too much $ spent in defense). But I'm pretty certain Ezekiel was not talking about the Holocaust that already happened.
As for fulfilling the 613 mitzvot, if you were able to do that, where does it say that it will save you from the wrath of God? Like Leviticus says, only the blood atones for sins, and without a Temple there hasn't been any sacrifices for 2,000 years. Only the blood of Yeshua HaMassiach can help you!
I do not agree with you. The books Shmiras HaLashon and the Chofetz Chayim detail how life and death are in the power of restraining one’s speech. Those books are both available with an English translation. Anybody who does not live near a Jewish bookstore and wants to read these books can order them online; and he should, because they can change his life for the better! The Chofetz Chaim, in English is incredibly good, but both books have the power to get him where he needs to be spiritually.
