¹ I say again: Has God cast away His people?
God forbid: For I am also an Israelite from the seed of Abraham of the tribe of Benjamin.

From chapter 10 through out  Chapter 11, Paul continues his effort to persuade the Jewish people that the Righteousness of Yeshua/Jesus is the Righteousness that can only save a person from their death sentence that their sin calls for. Paul is a natural seed of Abraham and he believes in the same TRUTH of Yahweh God's Salvation Son that gave Faith to Father Abraham.   Now let's consider the Graciousness of the TRUTH of Yahweh God, for in a vision Abram saw the innocent Son of Man conceived as the only begotten Son of God, to be of the very seed of his loins, suffer crucifixion death for the sin of mankind, but was Righteously raised from the dead, by the Power of LIFE in Yahweh God Almighty.  Yahweh God is Abraham's and Paul's Savior through the Gift of Yahweh's only begotten Son Yeshua haMashiach.  Yahweh Lord God Almighty, is Eternally Faithful to His WORD of TRUTH, and will preserve Paul from the judgment of Paul's fleshly nature through Paul's Faith in the LIFE Saving Blood of Jesus Christ. 

For I through the Law of sin am already dead because of the condemning law [of sin and death], so that now I may live unto God.  By Faith I am crucified with Christ, nevertheless I Live, yet not by my power, but by the Power of the LIFE of Christ, Who Lives IN me: And now the Life that I Live in my flesh, I Live by the faith of the Son of God who Loved me, and gave Himself for me. ^{(See Galatians 2 verse 19 thru 21.)}

² God has not cast away His people which He foreknew.  Do you not know what the scripture says of Elias? How Elias made intercession to God  against [according to]  Israel, and said:

Yahweh God was never against Israel, but His desire is that all men would be saved, and would receive His Grace through His Only Begotten Son conceived in the flesh of man. For the Man Christ Jesus was ordained before the foundation of the world as a Innocent Lamb to suffer death for mankind's sin and death, and to arise on the first day of the week in the resurrection LIFE of His Father Yahweh God.  From the first day of God's Creation through out the seven day week, Yahweh God is to be worshiped as the Creator of LIFE without end.

3 Lord, they have killed your prophets, and dragged down your altars; and I am left alone, and they seek my life.

⁴ But How does God answer him [Elias]? I have reserved to Myself seven thousand men, who have not bowed the knee to the image of Baal.

⁵ Then even so, at this present time there is also a remnant according to the election of grace.

⁶ And if by grace, then is it no more of works: otherwise grace is no more grace. But if grace be of works, then grace is no more grace: otherwise work is no more work.

⁷ What then? Israel has not obtained that which he sought for; but the election has obtained it, [a reserved remnant of men like the the seven thousand] and the rest were blinded unto this day.

⁸ According as it is written: God has given them the spirit of slumber, eyes that they should not see, and ears that they should not hear.

⁹ And David said: Let their table [of animal sacrifice] be made a snare, and a trap, and a stumbling block, and a reward for them:

¹⁰ Let their eyes be darkened, that they may not see, and bow down their back always, [in subjection to the animal sacrifices.]

¹¹ I say then: Have they stumbled that they should fall? God forbid: But rather [that] through their fall [through their blindness], salvation is come unto the Gentiles, so as to provoke the Jew to jealousy.

¹² Now if the fall of the Jews be the riches of the world, and the diminishing of the Jews be the riches of the Gentiles, then how much more shall be the fullness of the Jews?

¹³ For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, [for] I am magnifying my office,

¹⁴ If by any means I may provoke to emulation the Jews which are my flesh, and might save some of them.

¹⁵ For if the casting away of them be the reconciling of the world, then what shall the receiving of them be [when their blindness is healed], but Life from the dead?

¹⁶ For if the first fruit [Christ] be holy, the lump is also holy: and if the root is holy, then so are the [natural] branches [of Iarael].

The Lamb of God, born of the genetic son of Adam, as Jesus Christ the Man, is Yahweh God's Righteous FirstFruit of Yahweh's Resurrection Power of the Hebrew Man.

¹⁷ And if some of the natural branches be broken off, and you gentiles, being a wild olive tree, were grafted in among the natural branches, and with the natural branches partake of the root and fatness of the olive tree; then

¹⁸ Boast not against the natural branches. But if you boast, then know that you do not bear the root, but the root you.

Both the natural branches of  the natural olive tree and the grafted in wild olive branches will produce new growth in suckling branches that will need pruning so that the tree will produce more righteous fruit.  The branches that are healthy will love the sap of the living tree that flows throughout the branches.  However if the grafted in branches of the wild olive tree, assert their willful wildness, then the sap of the life in the natural olive tree, will cease to flow to the wild olive branches and death will ensue and the branches will wither and be broken off from the Tree that gives them LIFE.

¹⁹ You will say then: The Natural branches were broken off, that I might be grafted in.

²⁰ Well; because of unbelief the natural branches were broken off, and you stand by faith. Be not high-minded, but fear:

²¹ For if God spared not the natural branches, [because of unbelief] take heed lest He also spare not you.

Abiding in the Vine of Life.

I AM the TRUE Vine, and My Father is the Gardener. ² Every branch in Me that does not produce fruit, Yahweh takes away: And every branch that produces fruit, Yahweh prunes the branch so that it will produce more fruit. ⁴ Abide in Me and I will abide in you. Even as the branch can not produce fruit by itself, for the branch must abide in the Vine. You can not produce fruit unless you abide in the Me.  I AM the Vine, you are the branches. Without Me you bring forth no fruit [or nothing of value in the LOVE of Yahweh]. 6 If a man does not abide in Me, he is cast forth as a branch and withers, and men gather them up, and cast them into the fire.   ^{(See John  15 verse 1 thru 6.)}

²² Behold therefore the goodness and severity of God: On them which fell severity; but toward you gentiles, goodness, if you continue in His goodness: Otherwise you also shall be cut off.

²³ And also, if the Natural Branches do not continue in their unbelief, then the Jew shall be grafted into the Natural Tree: For God is able to graft them in again.

²⁴ For if you gentiles were cut out of an olive tree which is wild by nature, and were grafted contrary to nature into a good olive tree, then how much more shall the Jew, which be the natural branches, be grafted into their own olive tree?

²⁵ For brethren, I would not that you should be ignorant of this mystery, unless you should be wise in your own conceits, that blindness in part is happened to Israel, until the fullness of the Gentiles be come in.

²⁶ And so all Israel shall be saved, as it is written: There shall come out of Zion the Deliverer, and He shall turn away ungodliness from Jacob (Israel):

²⁷ For this is My Covenant unto them, when I shall take away their sins.

²⁸ As concerning to the gospel, the Jews are enemies for your sakes: But as touching the election, they are beloved for the Father's sakes.

Because of the unbelief of the natural Jew, their position on the Natural Olive Tree with its supply of LIFE from its Root, was made void.  Paul called the Jew the enemy of the gentiles because of the Jews naturally right position in the Olive Tree.  Their rightful place, would take away the place of the gentiles who would revert back to the wildness of the wild olive tree.

²⁹ For the gifts and calling of God are without repentance.

³⁰ For as in times past you [gentiles] have not believed God, yet now you have obtained mercy through the Jews unbelief.

³¹ Even so these [Jews] have not now [presently] believed, but through your mercy they also may obtain mercy.

³² For God has concluded the Jews are in unbelief, that He might have mercy upon all [peoples.]

³³ O the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments, and His Ways past finding out!

^{Psalm 145 verse 3} Great is the Lord, and greatly to be praised; and his greatness is unsearchable.

³⁴ For who has known the Mind of the Lord? Or who has been His counselor?

³⁵ Or who has first given to Him, and it shall be recompensed unto that person again?

³⁶ For of Him, and through Him, and to Him, are all things: To Him be Glory for ever. Amen.

The epistles of Paul, written about 2000 years ago, were fragmented and then pieced together in time, and now it appears there is a finalizing Amen that would bring to a conclusion the letter to the Romans. What is labeled as the 12th chapter of Romans, has writings that conforms to the 12th Chapter of 1st Corinthians dealing with gifts.
