Romans 11:16-22

If the first fruit is holy, so is the lump. If the root is holy, so are the branches. But if some of the branches were broken off, and you, being a wild olive, were grafted in amongst them and became partaker with them of the root and of the richness of the olive tree, don’t boast over the branches. But if you boast, remember that it is not you who support the root, but the root supports you. You will say then, “Branches were broken off, that I might be grafted in.” True; by their unbelief they were broken off, and you stand by your faith. Don’t be conceited, but fear; for if God didn’t spare the natural branches, neither will he spare you. See then the goodness and severity of God. Towards those who fell, severity; but towards you, goodness, if you continue in his goodness; otherwise you also will be cut off.
