In Romans 9-11, Paul brings up Israel as a test case for whether or not God lies. Paul must establish that God is not a liar in order for us to believe His high promises to us. Satan knows that Israel is the easiest target at his disposal to plant doubt in the minds of believers as to God's LITERAL promises. Unfortunately, many today help Satan further his lie by pushing a false teaching known as "Israel Replacement Theology," or "Preterism." Even Alan Hess promotes this lie.
