Paul tells us in Romans who a true Jew is and Galatians 6 that the Church is the Israel of God.
Slight problem with going to Galatians 6:16. EVERYONE but the Futurist knows that the "Israel of God" is to be distinguished from "Israel of the Flesh" (Romans 2:29; 4:12; 9:6,7). If the Futurists were to ever concede that there was a distinction, then they wouldn't be Dispensationalists. Being a Dispy is far more important than being faithful to the Scriptures.
amen. please accept my apology for not pinging you like i did lee n. field, i know you very good at defending orthodoxy against the dispensationalist heresy.
