Genesis 17:10 "Every male child among you shall be circumcised"

HaShem made the Jewish people special and different.

The Torah sets us apart from all other nations.

HaShem wants that special quality to be imprinted on our bodies to serve as a constant reminder and sign of our uniqueness.

He commanded that all males be circumcised.

Circumcision is called a brit, a covenant, connecting our people to HaShem.

If HaShem wanted us to be circumcised why didn't He create us circumcised from birth?

HaShem wants us to reach this state through our own efforts and actions.

Through our performance of this Positive Mitzvah, we establish this bond with HaShem.

The Study continues with Rambam "Order of prayers for the whole year. until "He shall reign over us etc."
