I think we’re well aware of Romans 11. In fact, the prayer in question is clearly based on it, and prays for its speedy fulfillment.
Very specifically: Romans 11 where he discusses who is grafted into whom.shalom b'shem Yah'shua
NAsbU Romans 11:17 But if some of the branches were broken off,Paul warns against the pride of a Gentile follower of Yah'shua.
and you, being a wild olive, were grafted in among them
and became partaker with them of the rich root of the olive tree,
NAsbU Romans 11:19 You will say then, "Branches were broken off
so that I might be grafted in."
NAsbU Romans 11:22 Behold then the kindness and severity of God;A Jew who comes to know the Jewish Messiah for their salvation
to those who fell, severity, but to you, God's kindness,
if you continue in His kindness; otherwise you also will be cut off.
NAsbU Romans 11:23 And they also, if they do not continue in their unbelief,
will be grafted in, for God is able to graft them in again.
does not become a Christian,
They become a "called out one", a member of the Ekklesia.
They become a Messianic Jew.The L-rd's name ( Shem ) is not je-zeus; it is Yah'shua ( YHvH is my salvation )
Which is why you must call on His Name for salvation.
But what's the point??? Will God cut short His timetable???
Rom 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 be come in.
God says don't be conceited in your self perceived wisdom...When God's plan is completed, He will lift the blinders from Israel...
Although I would agree that a Pastor or Priest should encourage his flock to privately pray for the Salvation of Israel, making it a policy of a religion could only lead to suspicion and scepticism from the Jewish nation...
I can understand their dismay at the turn of events...
