Thanks be to Jesus Christ, St.Pauls words for Israel went beyond what he wrote in Rom9:6. What a shame when people use Rom9:6 as a one-liner to show the low-place of where the Jews outside Christ stand.
If you are a Jew, please read St.Pauls words-
**Romans 9:1-5
I speak the truth in Christ—I am not lying, my conscience confirms it in the Holy Spirit— I have great sorrow and unceasing anguish in my heart. For I could wish that I myself were cursed and cut off from Christ for the sake of my brothers, those of my own race, the people of Israel. Theirs is the adoption as sons; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises. Theirs are the patriarchs, and from them is traced the human ancestry of Christ, who is God over all, forever praised! Amen.
Romans 10:1
Brothers, my heart’s desire and prayer to God for the Israelites is that they may be saved. **
If you are not a Jew, please read St.Pauls words.
Romans 11:17-21
If some of the branches have been broken off, and you, though a wild olive shoot, have been grafted in among the others and now share in the nourishing sap from the olive root, do not boast over those branches. If you do, consider this: You do not support the root, but the root supports you. You will say then, “Branches were broken off so that I could be grafted in.” Granted. But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but be afraid. For if God did not spare the natural branches, he will not spare you either.
