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 consider yourself to be superior to those other 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 tremble.
For if God did not spare the natural branches, he will not spare you either.
Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off.
And if they do not persist in unbelief, they will be grafted in, for God is able to graft them in again.
After all, if you were cut out of an olive tree that is wild by nature, and contrary to nature were grafted into a cultivated olive tree, how much more readily will these, the natural branches, be grafted into their own olive tree!
I do not want you to be ignorant of this mystery, brothers and sisters, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in,
and in this way all Israel will be saved. As it is written: “The deliverer will come from Zion; he will turn godlessness away from Jacob.
And this is my covenant with them when I take away their sins.”
