For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
Again, Saul is referring to those of his flesh aka Jews.
Jeremiah, you are just as blinded as the Jews were in Jesus' day. Notice Paul said clearly: "
For if the casting away of them be the reconciling of the world"~The Jews as a nation are forever cast off
as a nation, a very small, and I emphasis, a very small remnant are part of the children of Abraham...
The promise to build His Church [Greek: "ekklesia" = "called out [ones].") A direct reference to Israel as a "Great Congregation" in the desert at the time of the Tabernacle and beyond. Israel, as was with baby Jesus, were called out of Egypt.
65 And at that time Solomon held a feast, and all Israel with him, a
great congregation, from the entering in of Hamath unto the river of Egypt, before the LORD our God, seven days and seven days, even fourteen days.
1 Ki 8:65.
1 Furthermore David the king said unto all the
congregation, Solomon my son, whom alone God hath chosen, is yet young and tender, and the work is great: for the palace is not for man, but for the LORD God.
1 Ch 29:1.
25 My praise shall be of thee in the
great congregation:
I will pay my vows before them that fear him.
Psalm 22:25.
And on the day of the Jewish Feast of Harvest Jesus Christ through the Holy Spirit of Promise PROMISED TO ISRAEL BY JOEL began that building of His Church by delivering from sin three thousand Jews.
41 Then they that gladly received his word were baptized:
and the same day there were added unto them about three thousand souls.
Acts 2:41.
IF Israel was cast off as a nation why did Jesus begin the spiritual building of the natural Olive tree Israel with the saving of three thousand Jews? That is a very large number of maybe a million of attendees at this Jewish Feast circa AD 32. But there's more to become saved:
47 Praising God,
and having favour with all the people.
And the Lord added to the church daily such as should be saved.
Acts 2:47.
The Jews having favor with God and the people. And the Lord added thousands to His Church, that Great Congregation of Jews, daily "such as
should be saved." Imagine that. A nation you claim is "cast off" [and ended] comes roaring back with the personal salvation of thousands of Jews daily into the foundation of the Church of the Lord Jesus Christ. Seems to me Jesus Christ is not casting off but BUILDING a Church of "called out [ones]."
Thousands and thousands daily were being born-again, filled with the Holy Spirit of Promise and having favor with all the Jewish people as they began to see these events as fulfillment of Joel's prophecy of God giving His Spirit - which is necessary to salvation - to the Jews.
27 And ye shall know that
I am in the midst of Israel,
And that
I am the LORD your God, and none else:
And
my people shall never be ashamed.
28 And it shall come to pass afterward,
That I will pour out my spirit upon all [Hebrew] flesh;
And
your sons and
your daughters shall prophesy,
Your old men shall dream dreams,
Your young men shall see visions:
29 And also upon the servants and upon the handmaids
In those days will I pour out my spirit.
30 And I will shew wonders in the heavens and in the earth,
Blood, and fire, and pillars of smoke.
31 The sun shall be turned into darkness, and the moon into blood,
Before the great and the terrible day of the LORD come.
32 And it shall come to pass, that whosoever shall call on the name of the LORD shall be delivered:
For in mount Zion and in Jerusalem shall be deliverance,
As the LORD hath said,
And in the remnant whom the LORD shall call.
Joel 2:27–32.
It doesn't say "In Gentiles" or "among Gentiles" there will be salvation. It says "IN MOUNT ZION AND IN JERUSALEM" - possessions of the Jewish people, owners of the Promised Land that sees the salvation of the Lord.
Everyday going forward thousands and thousands of Jews being born-again in fulfillment of dozens of prophecies to Israel by God were being born-again and being filled with the Holy Spirit of Promise. And to whom was God's Spirit promised to?
To the Jewish people.
38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins,
and ye shall receive the gift of the Holy Ghost.
39
For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
40 And with many other words did he testify and exhort, saying, Save yourselves from
this untoward generation.
Acts 2:38–40.
I don't see the "casting off" of the Jewish people, but the
building and
re-building of this great congregation of people. Every day since the Feast of Harvest Jesus Christ is giving the Jewish people His Spirit and is building back up this great congregation of people. Don't you see this? Or, does Scripture hold nothing towards what you are to believe as the truth of God. Can you continue to say and believe the false teaching you claim of God "cast off" this nation of people?
Tell me.
