The only way this could be true, is to spiritualize, or make an allegory of many prophesies concerning Israel and her restoration. And make them somehow be fulfilled with the church. or when we all get to heaven. Which I believe is a dangerous thing, and makes a mockery of God and his promises, and his prophetic purpose. to prove he is the one true God.
Isaiah 10:
16 .) Therefore shall the Lord, the Lord of hosts, send among his fat ones leanness; and under his glory he shall kindle a burning like the burning of a fire.
17 .) And the light of Israel shall be for a fire, and his Holy One for a flame: and it shall burn and devour his thorns and his briers in one day;
18 .) And shall consume the glory of his forest, and of his fruitful field, both soul and body: and they shall be as when a standard-bearer fainteth.
19 .) And the rest of the trees of his forest shall be few, that a child may write them.
20 .) And it shall come to pass in that day, that the remnant of Israel, and such as are escaped of the house of Jacob, shall no more again stay upon him that smote them; but shall stay upon the LORD, the Holy One of Israel, in truth.
21 .) The remnant shall return, even the remnant of Jacob, unto the mighty God.
22 .) For though thy people Israel be as the sand of the sea, yet a remnant of them shall return: the consumption decreed shall overflow with righteousness.
Romans 9:
24 .) Even us, whom he hath called, not of the Jews only, but also of the Gentiles?
25 .) As he saith also in Osee, I will call them my people, which were not my people; and her beloved, which was not beloved.
26 .) And it shall come to pass, that in the place where it was said unto them, Ye are not my people; there shall they be called the children of the living God.
27 .) Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved:
Matthew 5:
20 .) For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
John 14:
6 .) Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
7 .) If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.
Romans 10:
1 .) Brethren, my heart's desire and prayer to God for Israel is, that they might be saved.
Romans 11:
23 .) And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
And many, many more.........yeah.......Jesus, Isaiah, Paul and others were guilty of "spiritualizing and making allegories."
