Why don't Christians ever claim to be following the God of the Jews? Most ofthe time, Christians claim to be following the God of the Christians! It just boggles my mind! In my understanding, I suppose this is one of the reasons why it was so easy to persecute the jews back in the day. If we all knew and believed that we were following the same diety, you'd think that we wouldn't feel it necessary to treat our "brothers" so poorly.
Yeshua claims the Abrahamic God is his father. He wanted us to follow his father. His father was God of the Jews.... So I think that he wanted us to be good Jews. Yeshua never says, "be good christians... and murder Jews when you feel like it"
Ahhh....so now we're getting to the real crux of your question.
I'm afraid you are painting all Christians in a very unfair light. The truth of the matter is that Christians
do follow the God of Abraham, Isaac, and Jacob. Most definitely! It is deplorable, I'll admit, that some "Christians" have persecuted Jews----but they are the exception to the rule, and very, very misguided.
Of course Yeshua doesn't tell us to be good Christians----because the term "christian" hadn't been invented during His lifetime on earth. It was a derisive term coined by Gentiles for His followers. But neither does Yeshua tell people to be good Jews.
Your logic is a bit misguided, but I can totally understand why. You see, the term "God of the Jews" was only used to differentiate Him from all the other false gods being worshiped by the pagan nations. The Jews were chosen by God to be a light among the nations, and to reveal who the True God really was. If you read the Scriptures you will see that the Jews repeatedly referred to Him as the "One True God," thus implying all other gods are false. So, the term "God of the Jews" does not really mean He belongs to the Jews and to no one else. The One True God doesn't "belong" to anyone! But the Jews, understandably, as His chosen people, began to see' Him as their own and no one else's. So Jesus, or Yeshua, came along and shattered all these notions. If Yeshua is God, the One True God, then He is the God not only of the Jews, but of anyone who believes in Him. For the One True God is not held captive by any one people group----rather, He transcends
all people groups. Does this make sense?
