From the New Testament. Does this sound like God has washed his hands of His people for all time?

Before, God, I will always stand for Israel against the demonic forces arrayed to wipe her from the face of the earth

. The Apostle Paul’s letter to the Romans 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 fulness of the Gentiles be come in.

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:

27 For this is my covenant unto them, when I shall take away their sins.

28 ¶ As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes.

29 For the gifts and calling of God are without repentance.

30 For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:

31 Even so have these also now not believed, that through your mercy they also may obtain mercy.

32 For God hath concluded them all in unbelief, that he might have mercy upon all.
