I agree with that.
Here's what I'm trying to understand about unbelieving Israel. Since the Messiah showed up and didn't set up the kingdom that was prophesied and if they're still God's people, what are their options?
That's the thing. During this Mystery Age they are NOT His people.
Neither as a nation nor as individuals.
Not during this age.
This age began with their status being as described in the following passages.
.
A warning Unbelieving Israel failed to heed....
Matthew 12:30 He that is not with me is against me; and he that gathereth not with me scattereth abroad. 12:31 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. 12:32 And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come. 12:33 Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by his fruit. 12:34 O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. 12:35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things. 12:36 But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. 12:37 For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
Even earlier, the Lord had told the Twelve....
Matthew 10:16 Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves. 10:17 But beware of men: for they will deliver you up to the councils, and they will scourge you in their synagogues; 10:18 And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles. 10:19 But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak. 10:20 For it is not ye that speak, but the Spirit of your Father which speaketh in you. 10:21 And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death. 10:22 And ye shall be hated of all men for my name's sake: but he that endureth to the end shall be saved. 10:23 But when they persecute you in this city, flee ye into another: for verily I say unto you, Ye shall not have gone over the cities of Israel, till the Son of man be come.
You see that? It would be the Spirit that would be speaking through them.
Early Acts begins to describe their persecution at the hands of Unbelieving Israel in their resistence of the Spirit, just as the Lord had told them.
Six chapters into it we read....
Acts 6:8 And Stephen, full of faith and power, did great wonders and miracles among the people. 6:9 Then there arose certain of the synagogue, which is called the synagogue of the Libertines, and Cyrenians, and Alexandrians, and of them of Cilicia and of Asia, disputing with Stephen. 6:10 And they were not able to resist the wisdom and the spirit by which he spake. 6:11 Then they suborned men, which said, We have heard him speak blasphemous words against Moses, and against God. 6:12 And they stirred up the people, and the elders, and the scribes, and came upon him, and caught him, and brought him to the council, 6:13 And set up false witnesses, which said, This man ceaseth not to speak blasphemous words against this holy place, and the law: 6:14 For we have heard him say, that this Jesus of Nazareth shall destroy this place, and shall change the customs which Moses delivered us. 6:15 And all that sat in the council, looking stedfastly on him, saw his face as it had been the face of an angel.
Who's Word were they really resisting? Who were they really slandering?
Acts 7:51 Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye. 7:52 Which of the prophets have not your fathers persecuted? and they have slain them which shewed before of the coming of the Just One; of whom ye have been now the betrayers and murderers: 7:53 Who have received the law by the disposition of angels, and have not kept it. 7:54 When they heard these things, they were cut to the heart, and they gnashed on him with their teeth. 7:55 But he, being full of the Holy Ghost, looked up stedfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God, 7:56 And said, Behold, I see the heavens opened, and the Son of man standing on the right hand of God.
In their failure to believe the Law of Moses the Spirit's Words to them through Stephen are based on, they resist the Spirit just as their fathers had before them.
They have been concluded having continued in the UNCircumcision of heart of their forefathers.
Paul will say more on this in Romans 2, etc.
And Stephen sees the Lord NOT sitting BUT standing.
Meaning?
Isaiah 14:21 Prepare slaughter for his children for the iniquity of their fathers; that they do not rise, nor possess the land, nor fill the face of the world with cities.
Isaiah 14:22 For I will rise up against them, saith the LORD of hosts, and cut off from Babylon the name, and remnant, and son, and nephew, saith the LORD.
Isaiah 28:21 For the LORD shall rise up as in mount Perazim, he shall be wroth as in the valley of Gibeon, that he may do his work, his strange work; and bring to pass his act, his strange act.
Isaiah 33:10 Now will I rise, saith the LORD; now will I be exalted; now will I lift up myself.
Israel was now headed toward the Day of the LORD - IN - HIS - WRATH - PRIOR - TO - HIS - MERCY - UNTO - THEM.
Isaiah 59:13 In transgressing and lying against the LORD, and departing away from our God, speaking oppression and revolt, conceiving and uttering from the heart words of falsehood. 59:14 And judgment is turned away backward, and justice standeth afar off: for truth is fallen in the street, and equity cannot enter. 59:15 Yea, truth faileth; and he that departeth from evil maketh himself a prey: and the LORD saw it, and it displeased him that there was no judgment. 59:16 And he saw that there was no man, and wondered that there was no intercessor: therefore his arm brought salvation unto him; and his righteousness, it sustained him. 59:17 For he put on righteousness as a breastplate, and an helmet of salvation upon his head; and he put on the garments of vengeance for clothing, and was clad with zeal as a cloak. 59:18 According to their deeds, accordingly he will repay, fury to his adversaries, recompence to his enemies; to the islands he will repay recompence. 59:19 So shall they fear the name of the LORD from the west, and his glory from the rising of the sun. When the enemy shall come in like a flood, the Spirit of the LORD shall lift up a standard against him. 59:20 And the Redeemer shall come to Zion, and unto them that turn from transgression in Jacob, saith the LORD. 59:21 As for me, this is my covenant with them, saith the LORD; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed's seed, saith the LORD, from henceforth and for ever.
As Paul wrote...
Romans 2:24 For the name of God is blasphemed among the Gentiles through you, as it is written. 2:25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
Unbelieving Israel was concluded in UNCircumcision - in other words "under sin" with the Gentiles.
But instead of His having allowed that to continue its' Prophesied course, we read....
Romans 9:22 What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction: 9:23 And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory, 9:24 Even us, whom he hath called, not of the Jews only, but also of the Gentiles?
Romans 11:7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded.
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. 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: 11:27 For this is my covenant unto them, when I shall take away their sins. 11:28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes. 11:29 For the gifts and calling of God are without repentance. 11:30 For as ye in times past have not believed God, yet have now obtained mercy through their unbelief: 11:31 Even so have these also now not believed, that through your mercy they also may obtain mercy. 11:32 For God hath concluded them all in unbelief, that he might have mercy upon all.
In short, with that, any Jew wanting salvation this side of God's having sealed their nation's Believing remnant, and concluding the rest in UnBelief or spiritual UNCircumcision, now had to come to Him as Gentile through Paul's "gospel of the uncircumcision."
Romans 3:9 What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin; 3:10 As it is written, There is none righteous, no, not one: 3:11 There is none that understandeth, there is none that seeketh after God.
Galatians 2:15 We who are Jews by nature, and not sinners of the Gentiles, 2:16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. 2:17 But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid. 2:18 For if I build again the things which I destroyed, I make myself a transgressor. 2:19 For I through the law am dead to the law, that I might live unto God.
As you can see, these things take more than a passage or two as to what's what.
