There is no "spiritual Israel".....
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 fulness 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.
Rev 11:1 And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein.
Rev 11:2 But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.
Rev 11:3 And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
There will be a spiritual Israel on earth,and Israel is the Church.
Israel is blinded in part,they acknowledge the Old Testament,but not the New,for the majority,but the nation of Israel must come to the truth.
Until the fulness of the Gentiles be come in,when salvation is no longer available to them when they take the mark of the beast at the beast kingdom.
And so all Israel shall be saved,from physical attack after the 7 years period,and physical Israel will become spiritual Israel for they turned to Jesus.
For the gifts and calling of God are without repentance,and God said,I am the LORD,I change not,therefore you sons of Jacob are not consumed,and God has not cast away His people He once foreknew,and if the ordinances of heaven are in effect,the sun,moon,and stars,God's covenant is still with Israel.
Abraham is the father of many nations,and all are blessed that have the faith of Abraham,and Jesus said salvation is of the Jews,and a Gentile when saved is a Jew inward,and part of the commonwealth of Israel,and the millennial reign of Christ is given to the Jews,for the kingdom will be restored to them at that time,and the earth will pass away,and the 12 tribes of Israel,and the 12 apostles of the Lamb,are written in the New Jerusalem.
It is Israel all the way,from Abraham to the New Jerusalem,Old Testament given to the Jews,and New Testament given to the Jews,and millennial reign of Christ given to the Jews,and the New Jerusalem given to the Jews,and a Gentile can be a part of it who becomes a Jew.
Act 1:6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?
Act 1:7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
Act 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
Jer 46:27 But fear not thou, O my servant Jacob, and be not dismayed, O Israel: for, behold, I will save thee from afar off, and thy seed from the land of their captivity; and Jacob shall return, and be in rest and at ease, and none shall make him afraid.
Jer 46:28 Fear thou not, O Jacob my servant, saith the LORD: for I am with thee; for I will make a full end of all the nations whither I have driven thee: but I will not make a full end of thee, but correct thee in measure; yet will I not leave thee wholly unpunished.
Eze 39:25 Therefore thus saith the Lord GOD; Now will I bring again the captivity of Jacob, and have mercy upon the whole house of Israel, and will be jealous for my holy name;
Eze 39:26 After that they have borne their shame, and all their trespasses whereby they have trespassed against me, when they dwelt safely in their land, and none made them afraid.
Eze 39:27 When I have brought them again from the people, and gathered them out of their enemies' lands, and am sanctified in them in the sight of many nations;
Eze 39:28 Then shall they know that I am the LORD their God, which caused them to be led into captivity among the heathen: but I have gathered them unto their own land, and have left none of them any more there.
Eze 39:29 Neither will I hide my face any more from them: for I have poured out my spirit upon the house of Israel, saith the Lord GOD.
Israel is the Church,but because of their disobedience they lost the physical dominion on earth,but will get it back in the millennial reign of Christ,but God said there are Jews that abide in the truth,like there were Jews on His side when they were disobedient in the Old Testament.
God is not going to blame all Jews because some are disobedient,even if they are the majority,which God will not blame the Church if there is hypocritical Christians,and will not blame all the Gentiles because some are disobedient,even if it is the majority,for there are Gentiles that are disobedient,but the same truth of Jesus,and the Bible,has been preached to them,as to the Jews.
Disobedience of some Jews does not cause God to give up on them,but they lost the physical dominion temporarily,but will get it back.
