True Israel and the land promises

Joshua 21:43-45 ESV - "Thus the LORD gave to Israel all the land that he swore to give to their fathers. And they took possession of it, and they settled there. And the LORD gave them rest on every side just as he had sworn to their fathers. Not one of all their enemies had withstood them, for the LORD had given all their enemies into their hands. Not one word of all the good promises that the LORD had made to the house of Israel had failed; all came to pass."

Many Christians apply the "land promise" Scriptures of Genesis to modern day unbelieving Jews.  This presupposition plays out on in reality by meddling in Middle Eastern politics. However, in Joshua we see that the land promised to Israel has already been fulfilled.  To assume that a modern, unbelieving, anti-Christian nation will again inherit this land is to assume that God will bless an apostate nation whose identity is rooted in their rejection of Jesus Christ.

Not only that, the consequences of this viewpoint causes much unneeded conflict and unnecessary war, all based on a misreading of Scripture.

The blessings of God find their fulfillment ultimately in Christ, where we don't look for land to find peace, but we look to the LORD.

So, who are True Jews?  Who is True Israel?  Who is Abraham's offspring?  Galatians 3:29 says, "IF YOU ARE CHRIST'S, THEN YOU ARE ABRAHAM'S OFFSPRING, HEIRS ACCORDING TO THE PROMISE."  It's clear.  CHRISTIANS are Abraham's offspring, CHRISTIANS are heirs, because we are Christ's.  Modern day Israel does not believe in Christ.  Therefore, they are not Abraham's offspring and not heirs.
