People don't really understand what the "Old Covenant" was it seems !! What Covenant did Abraham make with God? Was it the Law? Of course not, that's just erroneous isn't it, Abraham created the PROMISE COVENANT with God not the Law Covenant. As Galatians 3 tells us, the Law was added 430 years later. Anyone thinking that THE LAW was ever the Covenant is just in error.
Gal. 3:16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
17 And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul(meaning the Law which came LATER never did away with THE PROMISE), that it should make the promise of none effect. 18 For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise.
So, do you still think the Law was ever a true Covenant between God and Israel? No, it was added in because of sin. No one can be justified by the law.
19 Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.
24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. 25 But after that faith is come, we are no longer under a schoolmaster.
So, was the PROMISED COMING a "New Covenant", no of course not, it was the original covenant of the PROMISED COMING of the Messianic Lamb of God.
So, you do not seem to understand Jesus' promised coming was the REAL Old Covenant, and his coming ended THE LAW which was added in because of sins. God divorced Israel because of unbelief and thus as Paul says in Romans 11 when they BELIVE AGAIN God will graft them back in. Lets see if you can read Zechariah 13:8-9 where God says 1/3 of Israel repents just before the DOTL that is shown to come in Zechariah 14:1-2. Paul stated God's callings are without repentance. So, Israel was called to be a part of the the coming Kingdom Age and that will happen after they repent and Jesus rules from Jerusalem for 1000 years.
Yes they are, you simply do not understand the scriptures that shows us this brother. God is shouting at you with 12 (which means fulness) Jewish names x 12,000 and you can't grasp that its ALL Israel who repent. Its not even debatable.
Don't run away from the full context, Romans chapters 9-11 are all one passage. Paul says ALL Israel will be saved, not every Jew, but Israel as the Kingdom Age Nation will be preserved. All you have to do is read, Zechariah 8:9 says 1/3 of the Jews REPENT. And Malachi 4:5 says Elijah returns before the Day of the Lord to turn Israel back unto God.
The rest is not relevant, we know God turned His back on Israel until 1948, that's what the Ezekiel chapter 37 prophetic Dead Men's Bones are all about, BUT.......You seem to not be able to understand prophecy in full, God says he will make those Dead Men's Bones LIVE AGAIN, and that he will bring the WHOLE HOUSE of Israel back into the land in the end times and put LIFE back into them in a spiritual sense also. He BREATHES on Israel and they are quickened by His Spirit.
