15 For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
16 For if the firstfruit are holy, the lump is also holy: and if the root is holy, so are the branches.
17 And if some of the branches were broken off, and you, being a wild olive tree, were grafted in among them, and with them partake of the root and fatness of the olive tree;
18 Boast not against the branches. But if you boast, you bear not the root, but the root you.
19 You will say then, The branches were broken off, that I might be grafted in.
20 Well; because of unbelief they were broken off, and you stand by faith. Be not arrogant, but fear:
21 For if God spared not the natural branches, take heed lest he also not spare you.
