Romans 11 11-36
Ezekiel 37
It applies to Gentiles because Gentiles were grafted in due to the previous branch dying due to sin. Now this was done to bring salvation to the world as Paul says and to also provoke the Jews to jealousy that some might be won.
In
Ezekiel 37 21 then say to them, Thus says the Lord God: Behold, I will take the people of Israel from the nations among which they have gone, and will gather them from all around, and bring them to their own land. 22 And I will make them one nation in the land, on the mountains of Israel. And one king shall be king over them all, and they shall be no longer two nations, and no longer divided into two kingdoms. 23 They shall not defile themselves anymore with their idols and their detestable things, or with any of their transgressions. But I will save them from all the backslidings[
f] in which they have sinned, and will cleanse them; and they shall be my people, and I will be their God.
The way you speak its as if they will get some kind of "get out of jail free" card but God does not save and cleanse unrepentant sin which goes back to my original comments about them obeying the words of Peter.
Jesus already told the Jews of His day that," If you were the sons of Abraham, you'd do the works of Abraham."
So we already see that there is no free pass given to disobedience no matter what people call themselves.
Ezekiel 37 also speaks of every tribe becoming one as in the examples of the separate sticks representing the separate tribes and houses coming together to become one house.
It also speaks of covenants and again replace the word covenant with contract and then you understand that covenants are not one sided...both parties agree to behave and operate by certain standards of behavior the violation of which renders such covenant null and void which again God speaks of in Ezekiel when He compares Israel to a valley of dead dry bones. The whole chapter is about the restoration of Israel, how? By God putting HIS SPIRIT inside THEM.
He also speaks of "no man needing to teach you" in what you posted which is referenced in the letter from
1 John 2:27 and we are able to see that this is written to the Church who had been grafted in who no longer needed anyone to teach them because of
But the anointing which ye have received from Him abideth in you, and ye have no need that any man teach you. But as the same anointing teacheth you of all things, and is truth and is no lie, and even as it hath taught you, ye shall abide in Him.
