In Romans 4 we are told:
13 For the promise that he would be the heir of the world (kosmos) was not to Abraham or to his seed through the law, but through the righteousness of faith.With believers in Jesus Christ being identified as the true children of Abraham (Gal 3:28,29), and Abraham said to be the heir of the entire world, and that ultimately the inheritance of Abraham's children is spiritual in nature, how is it that some so-called prophecy experts put so much emphasis on a future, physical Israel?
