Romans 11:19

17But 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 root and of the richness of the olive tree,

18don’t boast over the branches. But if you boast, remember that it is not you who support the root, but the root supports you.

19You will say then, “Branches were broken off, that I might be grafted in.”

20True; by their unbelief they were broken off, and you stand by your faith. Don’t be conceited, but fear;

21for if God didn’t spare the natural branches, neither will he spare you.
