I cannot take credit for the following, as I can't for most of what I post... nothing new under the sun, right... But this was so good I copied it and kept it -
But if some of the branches(Physical Jews) were broken off, and you, a wild olive shoot(Elect Gentiles), were grafted in their place to share the richness/rich root (Jesus the Christ) of the olive tree(God's people), do not boast over the branches(Physical Jews). If you do boast, remember it is not you that support the root(Christ), but the root(Christ) that supports you. You will say, “Branches(Physical Jews) were broken off so that I might be grafted in.” That is true. They were broken off because of their unbelief, but you stand fast only through faith. So do not become proud, but stand in awe. For if God did not spare the natural branches(Physical Jews), neither will he spare you. Note then the kindness and the severity of God: severity toward those who have fallen, but God’s kindness to you, provided you continue in his kindness; otherwise you too will be cut off. And even the others(Physical Jews), if they do not persist in their unbelief, will be grafted in, for God has the power to graft them in again. For if you have been cut from what is by nature a wild olive tree(Gentiles), and grafted, contrary to nature, into a cultivated olive tree(God's people), how much more will these natural branches(Elect Jews) be grafted back into their own olive tree(God's people). Lest you be wise in your own conceits, I want you to understand this mystery, brethren: a hardening has come upon part of Israel(Physical Jews), until the full number of the Gentiles come in, and so all Israel(elect Jews & elect Gentiles) will be saved; as it is written, “The Deliverer will come from Zion, he will banish ungodliness from Jacob”; “and this will be my covenant with them when I take away their sins.” (Rom 11:17-27 RSV)
But it is not as though the word of God had failed. For not all who are descended from Israel belong to Israel, and not all are children of Abraham because they are his descendants; but “Through Isaac shall your descendants be named.” (Rom 9:6-7 RSV)
For he is not a real Jew who is one outwardly, nor is true circumcision something external and physical. He is a Jew who is one inwardly, and real circumcision is a matter of the heart, spiritual and not literal. His praise is not from men but from God. (Rom 2:28-29 RSV)
But far be it from me to glory except in the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world. For neither circumcision counts for anything, nor uncircumcision, but a new creation. Peace and mercy be upon all who walk by this rule, upon the Israel of God. (Gal 6:14-16 RSV)
