If one understands scripture, Paul makes it very clear that true "Israel" are those who repent and put their faith in Christ alone (as does Hebrews) those true "Israeilites" were always the ones who had faith in The one true God and were awaiting His Messiah. Most of the flesh of Abraham rejected the Messiah even in the OT and to this day reject the Lord Christ. Jerusalem was flattened literally as judgment for that national sin and the "jews" were dispersed among the nations also in judgement. So all true Christians are grafted in and have become "true Israel" the "seed of Abraham" who by faith became their father.
