Romans 11:17-21

But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the rich root of the olive tree,

do not be arrogant toward the branches; but if you are arrogant, remember that it is not you who supports the root, but the root supports you.

You will say then, “Branches were broken off so that I might be grafted in.”

Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear;

for if God did not spare the natural branches, He will not spare you, either.
