Romans 11:13-24 - Gentile Branches Grafted In
13 But I say to you, Gentiles, in so far as I am the Apostle of the Gentiles, I make much of my position: 14 If in any way those who are of my flesh may be moved to envy, so that some of them may get salvation by me. 15 For, if by their putting away, the rest of men have been made friends with God, what will their coming back again be, but life from the dead? 16 And if the first-fruit is holy, so is the mass: and if the root is holy, so are the branches.
17 But if some of the branches were broken off, and you, an olive-tree of the fields, were put in among them, and were given a part with them in the root by which the olive-tree is made fertile, 18 Do not be uplifted in pride over the branches: because it is not you who are the support of the root, but it is by the root that you are supported. 19 You will say, Branches were broken off so that I might be put in. 20 Truly, because they had no faith they were broken off, and you have your place by reason of your faith. Do not be lifted up in pride, but have fear; 21 For, if God did not have mercy on the natural branches, he will not have mercy on you. 22 See then that God is good but his rules are fixed: to those who were put away he was hard, but to you he has been good, on the condition that you keep in his mercy; if not, you will be cut off as they were. 23 And they, if they do not go on without faith, will be united to the tree again, because God is able to put them in again. 24 For if you were cut out of a field olive-tree, and against the natural use were united to a good olive-tree, how much more will these, the natural branches, be united again with the olive-tree which was theirs?
