By the way, I have studied the Abrahamic Covenant in the Bible (not in your Jewish commentaries or your Dispensationalist commentaries), and what came before that, and what came between the Law and Christ, and what came since then.
Newsflash: There's always only been one Israel, its election based on faith in the Word of God like Abraham had. God did not create a separate Israel when most of the genetic seed broke themselves off through their unbelief the way their forefathers had done when they perished in the wilderness. God took the Gentiles who believed in Christ, and joined them to the remnant of the natural seed who believed, but the root (Christ) remained. Same Israel, BUT THIS TIME the individual citizens are the living stones who together make a new Temple.
You need to study the covenants of God properly, after you've removed the dispense with the blood of Christ, sensational (Dispensational) lenses that are blinding you.
This is correct my friend . IT was always by faith . the covenant in abraham was always by Faith .
And there was a faithful rememnat of jews that always believed and did have that faith and they LOOKED for the PROMISE of HIS COMING .
And now GOD has opened this door unto the gentiles to have the same access into that tree .
And he will surely cast out anyone , whether jew or gentile who does not walk according to the Faith of Christ .
God never removed His own tree , He simply cast out of it those who rejected JESUS and grace was given unto the gentiles as well
to enter into that same TREE . And if they , the jews , continue not in unbeleif then they sure can be grafted back into that tree .
The covenant given unto abraham , POINTED TO THE PROMISE OF GOD , FOUND IN JESUS CHRIST and it was BY FAITH .
We must double down in those bibles . Learn that Christ , learn those words , learn all that sound doctrine by the HOLY GHOST
which dwells in the true lambs which consists of believing jews and believing gentiles . The wall of partition is broken down in JESUS .
And there simply is no other hope for a jew or a gentile than to HOLD TO CHRIST and let us love , adorn the doctrine of truth in those bibles .
