chosen people?

My word teaches you that I chose a certain people to represent me on earth, the nation of Israel. Do you assume that this mantle now falls to all Christians collectively? I didn’t claim the Jews for their own sake or for exclusivity, but that they should be a light for all the nations. I told my disciples that I had other sheep who were not of this fold. I was referring to you, and now I tell you the same thing. For I have also called you to let your light so shine before men that they may see your good works and glorify me. So I didn’t choose you for exclusivity any more than I chose Israel. Continue to let your light shine to penetrate and overtake the darkness.
