Then quit quoting the Old Testament since it has nothing to do with your Christ. Go and take your marker and black out every quote in your NT that was ripped off from the Old Testament, because, as you said it, if everything in your new testament is brand new, then your Jesus can not be the Messiah spoken of by Moses, the Prophets & the Psalms. Therefore, it is hypocritical of you to quote from that which was spoken by the Word of God who is the true Messiah of Israel. Oh, and BTW, Hebrews 8:8-11 new covenant, rip it out, because according to your reasoning, that part was ripped off from the true Messiah of Israel as it is a direct quote taken from the Word of God that was spoken through Moses & Jeremiah.
Do you see how illogical & unbiblical your response now stands?
As Paul wrote, we are grafted into Israel, not the other way around, therefore, he also reminded us that ALL those covenants of promise spoken of in the Old Testament, through Messiah we become partakes and heirs of those covenants of promise that you say your Christ has replaced. Now what did Paul say about those who come preaching another Christ? I think you need to take some time and reflect because that page in your bible that separates and calls one old & one new, well that is a man made doctrine. And we know this because John 1:1 starts of "In the beginning" ... and ... "He was in the world and the world knew Him not" ... and ... "He came to His own, and His own did not receive Him" ... "AND THEN THIS SAME MESSIAH put on flesh and tabernacled with men."
And this ignorant confusion comes from one not having the wisdom & understanding to discern between the oral laws of Judaism, aka, the Talmud that Jesus & His Apostles were constantly rebuking & the Law (Torah) of the Word of God, the Messiah of Israel, who delivered Israel out of Egypt. That same Word of God who is the Messiah of Israel who died for the sins of the whole world so that all who come to believe the Messiah of Israel will be saved. Shalom
No where does it say we are grafted into Israel.
Ro 11:17 Now if some of the boughs are broken out, yet you, being a wild olive, are grafted among them, and became joint participant of the root and*fatness of the olive.
The olive tree has its roots, but are not Israel alone. The root is Christ, the Log of Life. They grew from that root, they are not the roots themselves. They flourish as we do when we remain in Him. They have been cut off, except for a remnant.
The book of Hebrews was written to a particular people, not Gentiles:
Hb 1:1 By many portions and many modes, of old, God, speaking to the fathers in the prophets, in the last of these days speaks to us in a Son,
The Fathers,
The Prophets,
To us (Jewish believers who alone have fathers, prophets and had the Lord’s presence among them)
If you try to insert the Gentile nations into this letter as being part of the audience, you unhinge the testimony of the truth of God through Paul, His only appointed apostle to the Gentiles.
Israel will inherit the earth, along with the royal, kingly priesthood over the nations of the earth according to promise. But no believer today will be a part of that covenant. It is on earth, ours is among the celestial host in heaven. Our allotment is in heaven, theirs is upon the earth.
This you should know.
