in the heat of battle

a sign of true smarts is when one can simplify a concept without losing any ideas involved along the way.
example:
In Jewish Tradition, When a child reaches the age where he can start talking you teach them to say,

"The Torah which was commanded to us through Moshe, is the inheritance of the congregation of Yaakov"

before even the alphabet!!!
whats amazing is this line teaches the Jewish Identity.
Our Identity is Torah.

I'll explain...

G-D created the world in a working order, trees, grass, water, planets, everything that exists in this incredible system. then He created People and made them in to 70 nations.
the world was working very nicely, when all of a sudden out of no-where G-D comes down to Egypt and makes a New nation, a 71st nation, the Jews.
He took us out of Egypt and gave us The Torah, 613 commandments.
why did G-D do this?

so.. to better understand this we need to better understand our origins.

Avraham is called "the first Jew" , so to understand what a Jew is we need to know who Avraham is.
Avraham came to the conclusion that there was one source, which created everything,G-D Himself. And Avraham served G-D to the best of his abilities for 99 years.
then one day G-D came to Avraham and said [paraphrasing] "This has all been very nice, but, if you want to do something that will bring the world towards its ultimate completion and purpose, here's a commandment."
you see, when one does a commandment, it shows that there is a commander.
G-D says "Make for me a sanctuary, and I will dwell with in THEM"
also, the angels sing "HOLY! HOLY! HOLY! the world is filled with Your glory"
also, the Psalmist writes "Your kingdom is the kingdom throughout ALL the worlds"
G-D's desire to create a world, was to have a dwelling place in the lowest[Finite] world.
for a finite world to express an infinite G-D.
so when one does a command, in this finite world they are expressing something beyond infinite.
everything in Judaism ties in with this concept,from the beginning till the arrival of Moshiach which is the complete revelation of G-D.
"No one will ask their brother 'Teach me of G-D.' for they will know G-D. For the knowledge of G-D will cover the earth, as the waters cover the ocean."

and this is all in that one line we teach to Our children.

the point of all this is to tell you
Don't be discouraged if you can't answer someone whose trying to play with your Identity.
The virtue of Our Rabbi's is their simplicity in how to DO the Torah.
True, one can get into incredibly difficult concepts with in Torah
But the point is simple .
