Who is Israel in God's eyes

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.
Rom 11:26  And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
Rom 11:27  For this is my covenant unto them, when I shall take away their sins.
Rom 11:28  As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes.
Rom 11:29  For the gifts and calling of God are without repentance.
Rom 11:30  For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:
Rom 11:31  Even so have these also now not believed, that through your mercy they also may obtain mercy. 
Rom 11:32  For God hath concluded them all in unbelief, that He might have mercy upon all.
Rom 11:33  O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!
Rom 11:34  For who hath known the mind of the Lord? or who hath been his counselor?
Rom 11:35  Or who hath first given to him, and it shall be recompensed unto him again?
Rom 11:36  For of him, and through him, and to him, are all things: to whom be glory for ever. Amen.
