Jacob or Israel?

This Shabbat, we continued reading the life story of Jacob-
And as we already saw, this was a story of constant conflicts, much sorrow and many challenges...thus, Jacob is known to us as a Patriarch of Galut- his life symbolically represents "Jew in Exile"-under constant fear of attack, dependant on external factors for his very survival, weak and unable to rely on himself...This is how we were seen for generations by all the Esaus of the past, who came to humiliate us in so many ways, knowing that we will not be able to defend ourselves.
Yet, Jacob remains faithful to his G-d and his great mission that he believes in despite all the miseries- "I don't deserve all the kindness and all the truth that You have done to your servant"- he pleas to Hashem- reminding his G-d- "And you had said-'I will surely do good with you and I will make your offspring like the sand of the sea which is too numerous to count'...Esau is approaching, with 400 armed men ready to wipe out this Jacob who only has his family with him- Esau remembers how this Jacob took away his birthright, and then stole his blessing...Jacob the cheater, "cheap Jew"! How often do we come across this picture- Jews are perceived as smart and cunny and are using all their talent to manipulate the world and to control it- Elders of Zion are still on the minds of so many as we are "the mafia of the world"! And of course, we have all the right to dismiss this claim as ridiculous and antisemitic...But let's try to look at it from a different perspective- "noblesse oblige"-as they say- NOBILITY OBLIGATES- and we are the Chosen people, we claim to be on a high moral plain, we have a MISSION to become the Light onto the nations, and bring Mashiach to the World...So, here comes Esau and his complain is all of a sudden so REAL- "Is THAT how you become blessed- by CHEATING?"
We left Jacob as he is about to face his brother...but before he will see physical Esau, he is yet to struggle with his spiritual Master- this mysterious Man, that struggles with Jacob in the middle of the night...And gives Jacob a blessing-
"Your name shall not be called Jacob, BUT ISRAEL- for you have striven with the Divine and with men and have overcome"
This change of name, we must note, somehow resolves the issue- after receiving the blessing, Jacob is embraced by Esau, kissed by him, and this hatred seems to be forgotten...Esau offers his brother to follow him, Jacob politely refuses...and the Medrash is telling us- he will come "to judge the mount of Esau" in the future...
What's the significance of this change of name, and why is it not changed ENTIRELY (as was the case with Avraham, who once was known as Avram)-we still remember Jacob by his old, Galut name...
It seems, Galut is not willing to depart so easily, it's mark is quite real, and we are still living by it's standarts- Jacob would not change overnight, and his decendants will have to struggle many a night, to finally see the Light of Mashiach! Jacob is the Patriarch of Galut- and in Galut you need to act "under circumstances", sometimes cutting corners here and there, not being quite honest and truthful...You accept the norms of society that is run by Esau, and you are dependant on his mercy...At some point this hopeless and pitiful image of a Jew in Galut will become so loathsome to his very own sons, so that many of them will leave the House of Judaism, looking for the proud image of Freedom and Justice under the banners of Communism or secular Zionism- only to see how futile were their promises, some generations later...Jacob can't be redeemed in it's anthisesis- Esau is not going to cure us from Galut, but he URGES us to BECOME ISRAEL! His angel is here to tell us-
FREE YOURSELVES FROM YOUR SELF-IMPOSED LIMITATIONS, you don't need to steal your blessings anymore - EARN THEM HONESTLY, as you deserve it!
I think, this question of our IDENTITY is the most important one to be asked in our most crucial period of history- DO WE ACT AS ISRAEL? DO WE ACKNOWLEDGE OUR BIRTHRIGHT AS A HUGE RESPONSIBILITY- TO OURSELVES AND TO THE WHOLE WORLD?
