Anonymis: We can still be a light unto the nations even if we preserve our physical separation. We definitely need to interact with Goyim in order for us to make a parnassah. When we interact with them finely and honestly, then we are being a light unto the nations. So too, when we visibly lead our lives spiritually and with deeper meaning, then we are also a light onto the nations. We don’t need to create new scientific inventions for us to be light onto the nations. Our ultimate purpose is to serve God and make Him happy, and not to just be light unto the nations.
