"He is NOT A JEW who is one outwardly, nor is circumcision that which is OUTWARD in the FLESH. Be he is a Jew who is one INWARDLY; and circumcision is that which is of the HEART, BY THE SPIRIT; not by the letter, and his praise is not from men, but from God (Romans 2:28-29, NASB)."
 
"For the promise to Abraham or to his descendants  that he would be HEIR OF THE WORLD was not through the Law, but through the righteousness of faith... it is by FAITH, in order that it may be in accordance with GRACE, so that the promise will be ... to those who are of the FAITH of Abraham... (Rom 4:13, 16 NASB)."
 
"...it is NOT THE CHILDREN OF THE FLESH who are children of God, but the children of the PROMISE who are regarded as descendants (Rom 9:8)."
 
Romans 9:25 quoting Hosea 2:23 - "I will call those who were NOT MY PEOPLE, 'My people,' and she was not beloved, 'Beloved.'"
 
 
"For THERE IS NO DISTINCTION BETWEEN JEW AND GREEK; for the same Lord is Lord of all, abounding in riches for all who call on Him; for WHOEVER will call on the name of the LORD shall be saved (Rom 10:12-13)."
 
"So then, THOSE WHO ARE OF FAITH are blessed with Abraham, the believer (Galatians 3:9)."
 
"There IS NEITHER JEW NOR GREEK ... for you are all one in Christ Jesus. And if you belong to CHRIST, then YOU ARE ABRAHAM'S DESCENDANTS, heirs according to promise (Gal 3:28-29)."
 
"...the Gentiles are fellow heirs and fellow members of the body, and fellow partakers of the promise IN CHRIST JESUS through the gospel (Eph 3:6)."
