The land would not belong to Jews even if they were a 100% match.
The land does not belong to the seedS (plural) of Abraham…meaning the descendants of Abraham. It belongs to ONE specific descendant (seed) of Abraham…Jesus Christ.
Galatians 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.”
Jesus actually owns the land.
Any humans living there are just borrowing it temporarily until Jesus decides that he wants to use it. If you are curious…Jesus is eventually going to land something called “New Jerusalem” on it that roughly equivalent to a square that is 1500 miles on each side, and from that location he is going to rule the entire Earth. Needless to say, everything on that spot is going to get crushed when New Jerusalem comes down from the sky and lands.
