Throughout the centuries, many have claimed that Jews have pointed to be the concept of chosenness as a attempt by us to flaunt supposed superiority and greatness. In reality, just the oppersite is true.
The concept of chosen people means not that Jews were chosen for special privilege, but for sacred responsability, more to be a licht into the nation, and also reflecting on HaShem's light of love and law.
The secred Jewish responability is to receive, learn, live and teach HaShem's word and His will.
This is not a easy task, it is a heavy burden, but we do this willingly and with joy.
