nor were they regathered after 2,000 years to their homeland spiritually.
You're begging the question here, but that's beside the point.
The Apostolic approach to the OT is metaphorical. You can't come away from practically any application of the law or prophets made by them with any other rational conclusion.
Just off the top of my head, some examples not yet mentioned:
It was never about oxen.
For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen? Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope. - 1 Corinthians 9:9-10
Isaac and Ishmael, Sarah and Hagar. Believers vs unbelievers, Israel vs the Church
Galatians 4:21-31
It was never about the descendants of Abraham, but about Christ
Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. - Galatians 3:16
In reality, the faithful nation was only a picture of God's Son in the earth. So now it's easier to see that the Exodus was never about the Jews. It was about Christ.
When Israel was a child, then I loved him, and called my son out of Egypt. - Hosea 11:1
And was there until the death of Herod: that it might be fulfilled which was spoken of the Lord by the prophet, saying, Out of Egypt have I called my son. - Matthew 2:15
And, of course, the straightforward identification of the Church as Zion and the Heavenly Jerusalem, which is here now.
Hebrews 12:22
The true Israel was always spiritual Israel.
You have to deny the Scriptures to say that isn't so. You can't accept the fact that a jot has indeed passed from the law, namely a commandment concerning the priesthood that would bar Christ from assuming His position as High Priest (Heb. 7) . A jot has passed, meaning that all has been fulfilled. Matthew 5:18
The OT is done. There is nothing left. That Zionist apartheid state that has usurped the name of Israel and stolen the Jewish identity and has propagandized and weaponized the OT is not the fulfillment of prophecy.
The Church is.
Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. - 1 John 3:2
