Be mindful of the warning that Paul gave in this passage from Romans 11: -
11I say then, have they stumbled that they should fall? Certainly not! But through their fall, to provoke them to jealousy, salvation
has come to the Gentiles.
12Now if their fall
is riches for the world, and their failure riches for the Gentiles, how much more their fullness!
13For I speak to you Gentiles; inasmuch as I am an apostle to the Gentiles, I magnify my ministry,
14if by any means I may provoke to jealousy
those who are my flesh and save some of them.
15For if their being cast away
is the reconciling of the world, what
will their acceptance
be but life from the dead?
16For if the firstfruit
is holy, the lump
is also
holy; and if the root
is holy, so
are the branches.
17And if some of the branches were broken off, and you, being a wild olive tree, were grafted in among them, and with them became a partaker of the root and fatness of the olive tree,
18do not boast against the branches. But if you do boast,
remember that you do not support the root, but the root
supports you.
19You will say then, “Branches were broken off that I might be grafted in.”
20Well
said. Because of unbelief they were broken off, and you stand by faith. Do not be haughty, but fear.
21For if God did not spare the natural branches, He may not spare you either.
22Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in
His goodness. 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 out of the olive tree which is wild by nature, and were grafted contrary to nature into a cultivated olive tree, how much more will these, who
are natural
branches, be grafted into their own olive tree?
25For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, . . . .
