Romans 11:25–27

The calling of God is irrevocable.

Abraham’s seed will go out to all the world. By faith he believed God. By faith His seed will be saved. They were blinded for a moment in time so that we could see.

What I am learning is this: Perhaps the very people I exclude, are the ones who carry the light--the candle--that will allow me to see. That will allow me to see the Grace of God. And the expansive reach of God's acceptance. To every single one of us. SabbathMoments 

Romans 11:25–27

25 For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that blindness in part has happened to Israel until the fullness of the Gentiles has come in. 26 And so all Israel will be saved, as it is written: “The Deliverer will come out of Zion, And He will turn away ungodliness from Jacob; 27 For this is My covenant with them, When I take away their sins.” The New King James Version

Mystery in this context, probably refers to three difficult issues that Paul discusses in the passage: Israel’s partial hardening, the inclusion of the Gentiles as part of God’s people, and Israel’s future role in God’s plan of salvation. 

Paul hopes that the Gentile Christians will not become proud or boastful of their inclusion into the people of God. 

The full number of the Gentiles likely alludes to predictions that one day all nations will worship Yahweh. This also could refer to the completion of the mission to reach all people with the gospel. Paul viewed his ministry to the Gentiles (non-Jewish people) as integral to the fulfillment of this plan. Election may refer to the nation of Israel proper—whether all of Abraham’s natural descendants, or only the elect individuals within ethnic Israel. Alternatively, it could refer to Israel as symbolic of God’s elect—all who are now part of God’s people (both Jews and Gentiles). 

Paul’s meaning here is widely disputed. Any interpretation has far-reaching implications for the Jews and their place in God’s future plans. “All Israel” may include all who had faith like Abraham prior to Jesus’ coming, or Paul could be looking ahead to a future conversion when the entire nation of Israel accepts Jesus as Messiah. “ All Israel” also could be understood as a symbolic group (of Jews and Gentiles), since Paul envisions all of God’s elect as part of a single tree. 

A deliverer will come is a quotation from Isaiah 59:20 originally refers to Yahweh, Paul seems to apply it to Christ . If Paul’s use of this psalm points to Christ’s second coming, then the statement that “all Israel will be saved” could refer to a future time when the entire nation accepts Jesus as Messiah. Here, it might point to the heavenly Jerusalem from where Christ will return as deliverer. In the larger context of Isaiah, the covenant is mediated by the Suffering Servant. Jesus is the fulfillment of this prophecy, acting as the intercessor between God and humanity. Faithlife Study Bible

It is far more natural to expect Israel, the natural branches, to be grafted in, than to expect Gentiles, the wild branches, to be included. If believers do not understand this mystery, chances are they will be wise in their own opinion, meaning they will be haughty and boast. 

The mystery is that Israel has been temporarily and partially hardened, but God has not rejected them. All Israel does not mean that every individual in the nation will turn to the Lord. It means that the nation as a whole will be saved, just as the nation as a whole (but not every individual in it) was now rejecting the Lord. The NKJV Study Bible

True grace seeks not to confine God’s favour. Those who find mercy themselves, should endeavour that through their mercy others also may obtain mercy. They are to be brought to believe in Christ, the true become one sheep-fold with the Gentiles, under Christ the Great Shepherd. Matthew Henry’s Concise Commentary

Isaiah 59:20 “The Redeemer will come to Zion,

And to those who turn from transgression in Jacob,”Says the LORD.

Isaiah 59:21 “As for Me,” says the LORD, “this is My covenant with them: My Spirit who is upon you, and My words which I have put in your mouth, shall not depart from your mouth, nor from the mouth of your descendants, nor from the mouth of your descendants’ descendants,” says the LORD, “from this time and forevermore.”

Jeremiah 31:34 No more shall every man teach his neighbor, and every man his brother, saying, ‘Know the LORD,’ for they all shall know Me, from the least of them to the greatest of them, says the LORD. For I will forgive their iniquity, and their sin I will remember no more.”

Luke 21:24 And they will fall by the edge of the sword, and be led away captive into all nations. And Jerusalem will be trampled by Gentiles until the times of the Gentiles are fulfilled.

Romans 12:16 Be of the same mind toward one another. Do not set your mind on high things, but associate with the humble. Do not be wise in your own opinion.
