GOD MADE ABRAHAM, NOT MOSES, THE "FATHER OF MANY NATIONS"
The difference was so clear one must have blindness to miss it. The law was temporary. The promise is eternal. Hebrews need deliverance from the law. While Gentiles need deliverance from idols. Hebrews had a covenant with God before Jesus came to confirm that covenant with them. Gentiles did not. It is from this fact that the difference in our witness to these is derived.
