17) “And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakes of the root and fatness of the olive tree:
18) Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.”
These two verses are a portion of the mystery of God that is mentioned, seven verses later, that pertains to the grafting of the branch of the wild olive tree into the good olive tree:
Romans 11:25: “For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits, that blindness in part is happened to Israel, until the fullness of the Gentiles [nations] be come in.”
There are five important questions that need to be answered correctly in order to understand the mystery of the verses in Romans chapter 11.
