Paul writes in chapter 9 that he is very sorrowful for the Israelites. He states is verse 2 and 3 (Amplified)...
2 That I have bitter grief and incessant anguish in my heart.
3 For I could wish that I myself were accursed and cut off and banished from Christ for the sake of my brethren and instead of them, my natural kinsmen and my fellow countrymen. [Exod. 32:32.]
He continues speaking of his "countrymen" and in verse 6 states (Amplified)...
6 However, it is not as though God's Word had failed [coming to nothing]. For it is not everybody who is a descendant of Jacob (Israel) who belongs to [the true] Israel.
Paul writes that it is not the "children of the flesh but of the promise are counted for the seed" further explaining that in verse 25 and 25 who receives the promise....
24 Even including ourselves whom He has called, not only from among the Jews but also from among the Gentiles (heathen)?
25 Just as He says in Hosea, Those who were not My people I will call My people, and her who was not beloved [I will call] My beloved. [Hos. 2:23.]
It is exciting to understand that despite your lineage that you can be a child of the promise. This is direct connection with the sermon preached by Peter on the Day of Pentecost in Acts 2:39...
For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
