If prophesy can be fulfilled spiritually, there was no need for Israel to return physically to their land from their Babylonian captivity.
Since you want to make the land (a physical place) spiritual instead of physical, one could just as easily make Bethlehem (a physical place) spiritual instead of physical.
Everything was physical up to and including Christ Jesus.
Everything afterwards in found IN CHRIST JESUS.
Christ Jesus is the fulfillment.
Rest is found in Christ Jesus, not a piece of land in the Middle East.
