Romans 11:16-22

Now if the first-fruit be holy, the lump also; and if the root be holy, the branches also. Now if some of the branches have been broken out, and thou , being a wild olive tree, hast been grafted in amongst them, and hast become a fellow-partaker of the root and of the fatness of the olive tree, boast not against the branches; but if thou boast, it is not thou bearest the root, but the root thee. Thou wilt say then, The branches have been broken out in order that I might be grafted in. Right: they have been broken out through unbelief, and thou standest through faith. Be not high-minded, but fear: if God indeed has not spared the natural branches; lest it might be he spare not thee either. Behold then the goodness and severity of God: upon them who have fallen, severity; upon thee goodness of God, if thou shalt abide in goodness, since otherwise thou also wilt be cut away.
