For one is not a Jew who is one outwardly, nor is circumcision something visible in the flesh. Rather, the Jew is one inwardly, and circumcision is of the heart—in Spirit not in letter. His praise is not from men, but from God.
Romans 2:28,29 TLV
Since Yeshua HaMaschiach came to transform us on the inside we need to cleanse the inside of the cup and then the whole thing will be clean. This is what the covenant is all about. There is no Old Testament and New Testament, the Father’s will all along is to have a people set apart (Holy) to him. We can’t be holy if we are full of darkness.
I Am the True Vine
Stay in Me, and I stay in you. As the branch is unable to bear fruit of itself, unless it stays in the vine, so neither you, unless you stay in Me. I am the vine, you are the branches. He who stays in Me, and I in him, he bears much fruit. Because without Me you are able to do naught! If anyone does not stay in Me, he is thrown away as a branch and dries up. And they gather them and throw them into the fire, and they are burned. If you stay in Me, and My Words stay in you, you shall ask whatever you wish, and it shall be done for you. In this My Father is esteemed, that you bear much fruit, and you shall be My taught ones.
As the Father has loved Me, I have also loved you. Stay in My love. If you guard My commands, you shall stay in My love,a even as I have guarded My Father’s commands and stay in His love. These words I have spoken to you, so that My joy might be in you, and that your joy might be complete. This is My command, that you love one another, as I have loved you. No one has greater love than this: that one should lay down his life for his friends.
You are My friends if you do whatever I command you. No longer do I call you servants, for a servant does not know what his master is doing. But I have called you friends, for all teachings which I heard from My Father I have made known to you. You did not choose Me, but I chose you and appointed you that you should go and bear fruit, and that your fruit should remain, so that whatever you ask the Father in My Name He might give you. These words I command you, so that you love one another.
John 15:1-17 TLV
And He said, ‘Let Me hide My face from them, Let Me see what their end is, For they are a perverse generation, Children in whom there is no trusting. They made Me jealous by what is not Ěl, They provoked Me with their worthless matters. But I make them jealous by those who are no people, I provoke them with a foolish nation. Deuteronomy 32:20,21 TLV
if somehow I might provoke to jealousy those who are my flesh and save some of them. For if their casting away is the restoration to favour of the world, what is their acceptance but life from the dead? Now if the first-fruit is set-apart, the lump is also. And if the root is set-apart, so are the branches. And if some of the branches were broken off, and you, being a wild olive tree, have been grafted in among them, and came to share the root and fatness of the olive tree, do not boast against the branches. And if you boast, remember: you do not bear the root, but the root bears you!
You shall say then, “The branches were broken off that I might be grafted in.” Good! By unbelief they were broken off, and you stand by belief. Do not be arrogant, but fear. For if Elohim did not spare the natural branches, He might not spare you either. See then the kindness and sharpness of Elohim: on those who fell sharpness, but toward you kindness, if you continue in His kindness, otherwise you also shall be cut off. And they also, if they do not continue in unbelief, shall be grafted in, for Elohim is able to graft them in again. For if you were cut out of the olive tree which is wild by nature, and were grafted contrary to nature into a good olive tree, how much more shall these who are the natural branches, be grafted into their own olive tree?
The Mystery of Israel’s SalvationFor I do not wish you to be ignorant of this secret, brothers, lest you should be wise in your own estimation, that hardening in part has come over Yisra’ěl, until the completeness of the nations has come in. Footnote: a Gen_48:19. And so all Yisra’ěl shall be saved, as it has been written, “The Deliverer shall come out of Tsiyon, and He shall turn away wickedness from Ya‛aqoḇ, and this is My covenant with them, when I take away their sins.” Rom 11:14-27 TLV
“But a Redeemer will come to Zion, and to those in Jacob who turn from transgression.” It is a declaration of Adonai. “As for Me, this is My covenant with them,” says Adonai: “My Ruach who is on you, and My words that I have put in your mouth, shall not depart from your mouth, or from the mouth of your offspring, or from the mouth of your children’s offspring,” says Adonai, “from now on and forever.”
Isa 59:20,21 TLV
Yisrael remains the first-born son of Elohim (not to be confused with Yacob (Jacob), who was in-fact the second-born son, but to whom Esau traded his birthright for a bowl of stew; rather, the descendants of Avraham are first described as the chosen people of Elohim) and we, the Goyim (Hebrew for Gentiles or Nations) are adopted through Yeshua HaMashiach (Jesus) Grafted into the True Vine. Notice the warning in verse 25, “so that you will not be wise in your own estimation“. Paul is warning the redeemed Goyim not to misunderstand the partial hardening that happened to Yisrael. Yeshua came when He did, at a time when Yisrael was partially hardened and Rome was in power so that He might lay down His Life as payment for all of our sins… to remove unrighteousness from Yacob and to take away their sins.
