except christians are also the sons of abraham, so those blessings are meant to apply to them too. a good part of the new testament deals with integration of jews and gentiles, including rebuking uppity jews who still thought they were too good to eat with gentile brethren (paul even publicly rebuked peter for this) or tried to enforce ritualistic laws on the gentiles (like circumcision or dietary restrictions). christian gentiles are equals to christian jews. non-christian jews are not part of god's chosen people anymore, although they still have a part to play in the timeline of this world. the evil jews who killed jesus and did not repent are the same ones who do evil today. that does not make all jews evil, in fact i'd say that the common jew has had to suffer the consequences of the actions of and are used by the evil ones just as much as the gentile.
