Gentiles Grafted In and a Warning Against Boasting — Romans

11I say therefore that they did not stumble in order that they might fall. May it not be! But by their trespass salvation has come to the Gentiles in order to make them envious. 12If their trespass means riches for the world and their loss means riches for the Gentiles, how much more will their fulfillment mean? 13Now I am speaking to you Gentiles. Inasmuch then as I am an apostle of Gentiles, I glorify my service. 14If somehow I may make my own flesh envious and may save some of them. 15For if their deprivation means the reconciliation of the world, what will their reception mean but life from the dead? 16If the firstfruits are holy, so also is the lump; and if the root is holy, so also are the branches. 17If some of the branches were broken off and you, being a wild olive tree, were grafted in among them and became a sharer of the root of the richness of the olive tree, 18do not boast over the branches. If you do boast, it is not you who carry the root but the root that carries you. 19You will say then, Branches were broken off in order that I might be grafted in. 20They were broken off because of unbelief, but you stand by faith. Do not be high-minded, but fear. 21For if God did not spare the natural branches, neither will he spare you. 22Behold therefore the kindness and the severity of God: severity toward those who have fallen, but kindness toward you, if you continue in the kindness; otherwise you also will be cut off. 23And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again. 24For if you were cut off from the olive tree that is wild by nature and were grafted contrary to nature into the cultivated olive tree, how much more will these, the natural branches, be grafted back into their own olive tree?
