The Future of Israel Demands It
In Paul’s day Gentiles were coming into the church in greater numbers than Jewish converts and in Romans 11, Paul reminded them, Romans 11:17 (NLT2) 17 But some of these branches from Abraham’s tree—some of the people of Israel—have been broken off. And you Gentiles, who were branches from a wild olive tree, have been grafted in. So now you also receive the blessing God has promised Abraham and his children, sharing in the rich nourishment from the root of God’s special olive tree.
But the time is coming when the natural branches will be grafted back into the olive tree Romans 11:23-24 (NLT2)
23 And if the people of Israel turn from their unbelief, they will be grafted in again, for God has the power to graft them back into the tree. 24 You, by nature, were a branch cut from a wild olive tree. So if God was willing to do something contrary to nature by grafting you into his cultivated tree, he will be far more eager to graft the original branches back into the tree where they belong.
This is a phenomenon that Paul expressly connects with the return of Christ.
That is the day when Israel will mourn over the One whom they pierced( Zechariah 12:10) and God will save them all( Romans 11:26)
