Romans 11:15-22

15For if the casting away of them is the reconciling of the world, what shall the receiving of them be, but life from the dead? 16And if the firstfruit is holy, so is the lump: and if the root is holy, so are the branches. 17But if some of the branches were broken off, and thou, being a wild olive, wast grafted in among them, and didst become partaker with them of the root of the fatness of the olive tree; 18glory not over the branches: but if thou gloriest, it is not thou that bearest the root, but the root thee. 19Thou wilt say then, Branches were broken off, that I might be grafted in. 20Well; by their unbelief they were broken off, and thou standest by thy faith. Be not highminded, but fear: 21for if God spared not the natural branches, neither will he spare thee. 22Behold then the goodness and severity of God: toward them that fell, severity; but toward thee, God’s goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.
