——>No, GOD did NOT remove his Covenant with Israel.
With the LITERAL Nation of Israel, He certainly did, permanently (not individual Jews that accept Christ).
Matthew 21:43Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof. 44And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder.
Romans 9 to 11 shows that he did not. Israel came under the cursing, and was forced to wander because of unbelief. We are now in the time of the Fullfilment of Ezikiel 37 and Jerimiha 31. The Resotoration of Isreal. The land being restored is the natural part. The Spiritual restoration is even more important. Israel as a nation still has to go through a time of greater trouble though.
