YHvH's larger plan of salvation, where His People are blinded for a time,shalom b'shem Yah'shua
in order to bring His salvation to the gentile nations.NAsbU Romans 11:15 For if their ( His Chosen People )And their ultimate salvation after a period of blindness is guaranteed by YHvH's covenant :
rejection is the reconciliation of the world,
what will their acceptance be but life from the dead?
NAsbU Romans 11:25 For I do not want you, brethren,
to be uninformed of this mystery--
so that you will not be wise in your own estimation--
that a partial hardening has happened to Israel until
the fullness of the Gentiles has come in;
26 and so all Israel will be saved; just as it is written (in Isaiah 59),
"THE DELIVERER WILL COME FROM ZION,
HE WILL REMOVE UNGODLINESS FROM JACOB."
27 "THIS IS MY COVENANT WITH THEM, WHEN I TAKE AWAY THEIR SINS."
28 From the standpoint of the gospel they are enemies for your sake,
but from the standpoint of God's choice they are beloved for the sake of the fathers;
29 for the gifts and the calling of God are irrevocable.
Rom 11:7 What then? Israel failed to obtain what it sought. The elect obtained it, but the rest were hardened,
Rom 11:8 as it is written, "God gave them a spirit of stupor, eyes that should not see and ears that should not hear, down to this very day."
Rom 11:9 And David says, "Let their table become a snare and a trap, a pitfall and a retribution for them;
Rom 11:10 let their eyes be darkened so that they cannot see, and bend their backs for ever."
Rom 11:11 So I ask, have they stumbled so as to fall? By no means! But through their trespass salvation has come to the Gentiles, so as to make Israel jealous.
Rom 11:12 Now if their trespass means riches for the world, and if their failure means riches for the Gentiles, how much more will their full inclusion mean!
As Catholics, we pray for the fulfillment of Rom 11:12 and Rom 11:25, which you cited.
