I have never been able to find in Paul's writings or any other scriptures where it states that the Church is Spiritual Israel. - Can you please supply Scripture quotes (in context). Thank you.
Okay,
Per Jesus
MT 7:21: Not everyone who says to me, ‘Lord, Lord’ will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven.
MT 8:11: I say to you that many will come from the east and the west and will take their places at the feast with Abraham, Isaac and Jacob, but the subjects of the kingdom will be thrown outside into the darkness, where there will be weeping and gnashing of teeth.
MT 10:32: Whoever acknowledges me before men, I will also acknowledge him before my Father in heaven, but whoever disowns me before men, I will disown him before my Father in heaven.
MT 11:6&13-14: Blessed is the man who does not fall away on account of me… For all the Prophets and the Law prophesied until John, and if you are willing to accept it, he is the Elijah who was to come.
MT 13:14-15: This people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and I would heal them.
MT 21:43: I tell you that the kingdom of God will be taken away from you and given to a people who will produce its fruit.
MT 23:37: O Jerusalem, Jerusalem, you who kill the prophets and stone those sent to you! How often I have longed to gather your children together, as a hen gathers her chicks under her wings, but you were not willing.
MT 28:18-19a: All authority in heaven and on earth has been given to me. Therefore, go and make disciples of all nations…
JN 6:40: My Father’s will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise him up at the last day.
JN 8:42, 44&56: If God were your Father, you would love me, for I came from God and now am here. I have not come on my own, but he sent me… You belong to your father, the devil, and you want to carry out your father’s desire. He was a murderer from the beginning, not holding to the truth, for there is no truth in him… Your father Abraham rejoiced at the thought of seeing my day; he saw it and was glad.
JN 10:16: I have other sheep that are not of this sheep pen. I must bring them also. They too will listen to my voice, and there shall be one flock and one shepherd.
JN 12:48a & 49b: There is a judge for the one who rejects me and does not accept my words… for the Father who sent me commanded me what to say and how to say it.
JN 16:1-2: All this I have told you so that you will not go astray. They will put you out of the synagogue. In fact, a time is coming when anyone who kills you will think he is offering a service to God.
Per Paul
RM 1:1-5: Paul, a servant of Christ Jesus… Through him we received apostleship to call people from among all the Gentiles to the obedience that comes from faith. (All passages may be condensed.)
RM 2:1-11, 23-29: God will give to each person according to what he has done… There will be trouble and distress for every human being who does evil, first for the Jew, then for the Gentile, but glory, honor and peace for everyone who does good, first for the Jew, then for the Gentile. For God does not show favoritism.
RM 2:23-29: You (Jews) who brag about the law, do you dishonor God by breaking the law? As it is written, “God’s name is blasphemed among the Gentiles because of you.”… A man is not a Jew if he is only one outwardly, nor is circumcision merely outward and physical. No, a man is a Jew if he is one inwardly; and circumcision is of the heart.
RM 3:1-9: What advantage then is there in being a Jew?… First of all, they have been entrusted with the very words of God… What shall we conclude then? Are we (Jews) any better? Not at all! We have already made the charge that Jews and Gentiles alike are all under sin.
RM 3:20-30: Therefore no one will be declared righteous in his (God’s) sight by observing the law; rather through the law we become conscious of sin… Where then is boasting? It is excluded. On what principle? On that of observing the law? No, but on that of faith. For we maintain that a man is justified by faith apart from observing the law. Is God the God of the Jews only? Is he not the God of Gentiles too? Yes, of Gentiles too, since there is only one God, who will justify the circumcised by faith and the uncircumcised through that same faith.
RM 4:16-18: Therefore the promise (salvation) comes by faith, so that it may be by grace and may be guaranteed to all of Abraham’s offspring–not only to those who are of the law but also to those who are of the faith of Abraham. He is the father of us all. As it is written, “I have made you a father of many nations.”
RM 9:1-16: I speak the truth in Christ… I could wish myself were cursed and cut off from Christ for the sake of my brothers, those of my own race, the people of Israel… From them is traced the human ancestry of Christ, who is God over all, forever praised! Amen. It is not as though God’s word had failed, for not all who are descended from Israel are Israel. Nor because they are his descendants are they all Abraham’s children… It is not the natural children who are God’s children, but it is the children of the promise who are regarded as Abraham’s offspring.
RM 9:23-24 & 30-33: What if he (God) did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory–even us whom he also called, not only from the Jews but also from the Gentiles?… What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; but Israel, who pursued a law of righteousness, has not attained it. Why not? Because they pursued it not by faith but as if it were by works. They stumbled over the “stumbling stone”. As it is written, “See, I lay in Zion a stone that causes men to stumble and a rock that makes them fall, but the one who trusts in him will never be put to shame.”
RM 10:1&12-13: Brothers, my heart’s desire and prayer to God for the Israelites is that they may be saved… For there is no difference between Jew and Gentile–the same Lord is Lord of all and richly blesses all who call on him, for “Everyone who calls on the name of the Lord will be saved.”
RM 11:1&7-8: …Did God reject his people? By no means! I am an Israelite myself, a descendant of Abraham… What then? What Israel sought so earnestly it did not obtain, but the elect did. The others were hardened.
RM 11:11-32: Because of their transgression, salvation has come to the Gentiles to make Israel envious. But if their transgression means riches for the world, and their loss means riches for the Gentiles, how much greater riches will their fullness bring! I am talking to you Gentiles, inasmuch as I am the apostle to the Gentiles. I make much of my ministry in the hope that I may somehow arouse my own people to envy and save some of them… You will say then, “Branches were broken off that I may be grafted in.” Granted, but they were broken off because of unbelief, and you stand by faith. Do not be arrogant… Otherwise, you also will be cut off. And if they do not persist in unbelief, they will be grafted in again… Israel has experienced hardening in part until the full number of the Gentiles has come in. And so all Israel will be saved… For God has bound all men over to disobedience so that he may have mercy on them all.
RM 15:15-16: God gave me (grace) to be a minister of Christ Jesus to the Gentiles with the priestly duty of proclaiming the gospel of God, so that the Gentiles might become an offering acceptable to God, sanctified by the Holy Spirit.
I can post the rest by Paul next time if you want, but I ran too long to include more in this post.
