How much weight, seriousness and focus does orthodox Judaism give to the prophecy of Isaiah 49:6:
It is too small a thing that thou shall be my servant to raise up the tribes of Jacob and restore the preserved of Israel: I have given thee for a light unto the Gentiles, that thou mayst be my salvation unto the ends of the earth.
In what ways do the Orthodox and Hasidim endeavor to be "a light unto the Gentiles"? I ask this from the perspective of someone to whom it seems the deeper someone is into Orthodox Judaism, the more they try to limit their contact and exposure to Gentiles as much as possible.
