Anyone who can't see the miracles by God and rather keeps talking about real Jews have accepted Jesus shows me they themselves are not 'in Christ'. The Jews in the OT didn't know Christ but many knew His Spirit.The nation of Israel came into existence in 1948.
This would have never happened If God had not intervened in world affairs after WW2.
Israel would have never survived the first year if God had not protected them from those who had the superior arms and man power.
This has been true for 77 years now.
Those who believe this is not God's chosen nation, who will accept the Messiah when He comes again, are just---I don't know what to call them.
Going against those who God is clearly defending, and turning to their own will instead, not God's, is a lost war.
