Jesus, Mary, and Joseph were the first Christians. They demonstrated the fulfillment of jewish laws, and the grafting of the gentiles into the Body of Christ.
Modern jews are the self-proclaimed spiritual descendents pharisees who crucified Christ. Who forfeit their rights to the promise God gave them by refusing to adhere to His law and His commandments. Who made themselves gods and who are now destined for destruction unless they repent of their sins, accept Christ as their savior, and join together in the Body of Christ.
Failing at that, the jews will be destroyed, and may God have mercy on them when they are.
