Recall what Apostle Paul taught in Romans 11 about God having put the spirit of stupor upon the majority of Paul's brethren the Jews. Paul showed when the fullness of the Gentiles comes in, that blindness will be removed, and that means when Lord Jesus returns. That points to the faithful Jews who actually love God, but simply have been spiritually blinded so The Gospel would go to the Gentiles like Paul said.
So I believe the majority of them will believe on Jesus Christ once their blindness is removed. Zechariah 12 shows them in mourning for Christ when that happens. As for the "synagogue of Satan", not so much, because those represent Satan's servants here on earth that worship him.
Yes I will go straight to your idea that the Jews will turn to Christ. ( the majority)
There is a lot of testimony about this, lets see if many of it is of any use to you. ( or how many posts, you continue to state, what I say is untrue, even though it is entirely scripture, versus your ideas from mainly the old testament, plus your own words mostly also.)
The word of God had to be first spoken to Israel, Israel turned away, the apostles turned to the Gentiles.
Paul testified both to the Jews and also to the Greeks, repentance toward God and faith toward our Lord Jesus Christ.
( Acts 20 shows how many thousands of Jews believed in Christ.)
First Paul shows unto them of Damascus, and Jerusalem, and all Judea, and afterwards to the Gentiles, for all to turn to God and repent...
Acts 13:46 Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we
turn to the
Gentiles.
Acts 20:21 Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ.
Acts 21:20 And when they heard it, they glorified the Lord, and said unto him, Thou seest, brother, how many thousands of Jews there are which believe; and they are all
zealous of the law:
Acts 26:2 But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the
Gentiles, that they should repent and
turn to God, and do works meet for repentance.
The gospel of Christ is the power of God unto salvation to everyone who believes, which was to the Jew first ( it was first preached to them) and also to the Greek. ( preached to the Greeks afterwards.)
But anguish goes to everyone who does evil. ( who does not believe in Jesus Christ) to the Jew first, and then to the Gentile.
Glory goes to every man that works good ( belief in Christ) to the Jew first and also to the Gentile.
Romans 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the
Jew first, and also to the Greek.
Romans 2:9 Tribulation and anguish, upon every soul of man that doeth evil, of the
Jew first, and also of the Gentile;
Romans 2:10 But glory, honour, and peace, to every man that worketh good, to the
Jew first, and also to the Gentile:
The apostles proved both Jews and Gentiles to all be under sin, as there was none righteous, none that sought after God. ( they are calling all to God)
The law said the things it said to them under it, so they are guilty before God. By the law is the knowledge of sin. But now the righteousness of God WITHUT THE LAW, is MANIFESTED, the righteousness of God which is by faith of Jesus Christ, unto and upon ALL THEM THAT BELIEVE, for THERE IS NO DIFFERENCE, all sinned, all fell short of the glory of God. ( now they are freely justified by HIs grace through the redemption in Christ Jesus.)
He is the God of the Jews and the Gentiles, which shall justify the circumcision by FAITH, and uncircumcision through FAITH. ( this ESTABLISHES THE LAW/OF FAITH.)...
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;
10 As it is written, There is none righteous, no, not one:
11 There is none that understandeth, there is none that seeketh after God.
Romans 3:19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
23 For all have sinned, and come short of the glory of God;
Romans 3:24 Being justified freely by his grace through the redemption that is in Christ Jesus:
Romans 3:29 Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also:
30 Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
31 Do we then make void the law through faith? God forbid: yea, we establish the law.
Romans 3:27 Where is boasting then? It is excluded. By what
law? of works? Nay: but by the
law of
faith.
