Observant Jews understand the Jewish sources -- the materials passed down from the time of Moses through today regarding the Jewish national revelation at Sinai. The interpretation you have seems to be based on the Helenistic theology of Christianity -- which in many ways is quite opposite to the revelation of God to the Jewish nation. So - what is the Jewish understanding of it?
- They entered into a lasting (eternal) covenant (agreement) with God whereby they became "a priestly state, a nation set apart" The distinctive Jewish laws are intended as fundamentaly different from those of others because they are part of that distinctive job that God gave the Jews. It may be worth noting that, while the normal Christian understanding is that sacrifice is needed as the atonement for sin the Jews were told otherwise by God -- FIrstly, the vast majority of Jewish sacrifices have nothing to do with sin They are offerings of celebration - the sharing of joy. Secondly - with respect to the sin sacrifice -- "the sacrifice of the sinner is an abomination" "sin" is a violation of morality / a crime / a deed that damages the world the slaughter of an animal can not be used as a bribe to God to hide moral culpability Instead -- the person must repair his morality, make up for crime, repair damage to the world.. Only once he has done such real repentance, after he is no longer "a sinner" then he comes with the sacrifice -- again - as an offering of fellowship with God.
Jewish answer: You clearly do not comprehend the ways of the Gd of Abraham It is about being aware of G-d on a daily basis and being different than those around us. By not being able to eat with non-Jews and (for men) looking different than the surrounding pagans of ancient times because of being circumcised, it made it much more difficult to assimilate into pagan cultures. In addition, a pig cannot be slaughtered in a kosher manner, it has no neck.
Added: a Christian lecturing Jews on what we should believe. The arrogance is sometimes astounding.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
