The scripture says that no one was perfected by the works of the law, but it also calls some under the law "righteous." Zachariah, the father of John the Baptist is one such example.
The passage by Paul that speaks of the Israel of God references Abraham as the father of the faith, yet Abraham was not an Israelite, but the grandfather of Israel.
Defining Israel as above also denies what the passage actually says:
28 Concerning the gospel they are enemies for your sake, but concerning the election they are beloved for the sake of the fathers. 29 For the gifts and the calling of God are irrevocable. 30 For as you were once disobedient to God, yet have now obtained mercy through their disobedience, 31 even so these also have now been disobedient, that through the mercy shown you they also may obtain mercy. 32 For God has committed them all to disobedience, that He might have mercy on all. Roman's 19:28-32
I'm pretty sure that this section of Paul's letter is not referring to believing Jews. How would believing Jews be disobedient to the gospel?
Defining Israel as only believing gentiles and believing Jews is the same error that lead to the acceptance of concentration camps and the mass extermination of Jews by a "Christian " nation, Nazi Germany.
The German Jews were killed by the so called Zionist Jews, as they feared the German Jews, as they were the ones who called the Zionist out in fact and only around 10 % of Jews were pro so called Zionist. That's why Hitler who was the greatest so called Zionist lover of all time in fact and he got rid of the Jewish Media in fact and only let his Zionist print media, it was all created to try and get more German Jews to come over to the Rothschild's Zionist creation and Lord Rothschild has said it was so publicly in fact.
The W Churchill explained what WW2 was all about on TV interview in 1965 before he died that month, he said it was all about winning Markets !
WC said that he could not care less that they were Nazis or did and his opinion was the same with the Communist.
People like Rothschild's and Co do not fear Nazis or Communist, because they created the morons in fact.
The Zionist Jews were coming into Hitler's office day in day out during the War and they had papers that gave them clear freedom and the majority of top people in the Nazi Army were Zionist Jews and 75 % of the Russian Communist Government were so called Zionist Jews.
There was no real problem with German Jews at all as they had been settling in Germany for 2000 years and the problem Jews were the ones who came from the East because they were driven out of Russia by the Monarch for being traitors to Russia and the so called Zionist were playing their Satanic games.
Hitler's Nazi religion is a type of Protestant load of dribble that is a creation of Jewish Talmud like dribble, they are like railway tracks that follow the same path with racial prejudice madness etc etc not to mention the Nazi swastika comes from very early Jewish and before dribble that they had. when I tried to look into all this back in the 80's I was blocked from seeking such information, they did not want anyone looking into such things at all.
I was given the 3rd degree What your name, were do your live ! You have no right to look into such things etc they were so angry that they threaten me.
But I thought that it was my right to seek out anything that I pleased ?
Well some feared that if one was to read such stuff that you would become a Nazi

. so lets just lets believe that Hitler was a very bad man and be done with it hey, as ignorance is bliss, but I was not just like most people who could not care less about history to give a dam about the foundations of everything, so you have a education on a subject and not just a childish indoctrination that I got from school days, as that's not worth a cracker.
So I can see the details in what is going on nowadays clearly with all their set agendas. I understand their workings as I am not oblivious to such, like the majority are.
False so called Jews ! remember the Bible points them out, they worked to undermine the true Jews and Christ Jesus mate.
They seek their Talmud that is far worse than anything that even the Nazi stooges claimed by far, but the majority of people are to ignorant to be bother to look into such.
