I'm grafted into the family of God.
We are grafted into the Blessing God promised to Abraham. We are not grafted into the people of Israel. The Ten Commandments belong to the people of Israel.
I'm a child of God
I'm a seed of Abraham. Gal 3:29. Rom 9:6-8
Abraham is the Father of all those who believe. Romans 4:9-12. Understand? We are saved by faith, not by works. We are not obligated to rest on the seventh day because that religious practice is associated with a covenant God made with Israel.
A child of promise like Isaac. Gal 4:28.
God has not cast away His people, but He has redefined "Israel" not by physical lineage, but by the "election of grace." This means that both Jews and Gentiles who believe are grafted into the one true "olive tree."
Romans 11:5 – "Even so then at this present time also there is a remnant according to the election of grace."
Romans 11:17-24 – This passage explains how branches (literal Israel) were broken off because of unbelief, and "wild olive" branches (Gentiles) were grafted in to partake of the "root and fatness of the olive tree."
Your interpretation is erroneous because Paul is not addressing the question you want him to address. He is answering his own questions. He asks rhetorical questions to answer objections to the Gospel. In Romans 11:1 he asks, "I say then, God has not rejected His people, has He? May it never be!" This is meant as an objection and can be reframed as an objection. "Paul, the gospel you preach can't be true because you are saying that God rejected his people." Paul's answer to the rhetorical question defends the Gospel. Is God's rejection of the Jews a logical implication of the gospel that Paul preaches?
Paul argues, no, God's rejection of the Jews is not a logical implication of the gospel. He has never rejected all of the Jews. He has always reserved for himself a remnant of the Jews. Paul includes himself in that group. The Same thing happened during Elijah's day when God told Elijah that “I have kept for Myself seven thousand men who have not bowed the knee to Baal.”
In Romans 11:11 he asks another rhetorical question, which logically follows from the previous question. "I say then, they did not stumble so as to fall, did they? May it never be! But by their transgression salvation
has come to the Gentiles, to make them jealous." This is intended to answer another objection to the gospel. Okay Paul, the gospel doesn't teach that God rejected the Jews, but if only a remnant of the Jews are saved, then you are saying that God is rejecting the nation of Israel.
In other words, the objection goes like this. Paul, the gospel can't be true because it says that God rejected Israel as a nation. And Paul argues in the negative. Although Israel transgressed against God, i.e. put Jesus on a cross, they didn't stumble so as to fall. Rather, the Gospel has come to the Gentiles to make them jealous.
The point is, Paul's answer to that question defeats your idea that God redefined Israel, because to redefine Israel is to say that Israel fell. And Paul says that Israel did not fail.
In the eyes of God, being a "Jew" is a matter of the heart and the Spirit, rather than an outward physical mark or national identity.
Romans 2:28-29 – "For he is not a Jew, which is one outwardly... But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter."
Galatians 6:16 – "And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God."
No, that isn't true. Paul isn't saying that outward Jews aren't Jews. He is talking about outward Jews when he says that inward Jews are pleasing to God. We understand Romans 2:28-29 in the context of his opening line in verse 17, "17 But if you bear the name “Jew” and rely upon the Law and boast in God, " Among those people, the Jew is one inwardly. He is not suggesting that everyone who has a circumcised heart is a Jew inwardly. That isn't true. A true Jew keeps the entire law, not just a few of the ones they like.
Before we knew Christ, we were considered strangers to the covenant. However, through His blood, we have been adopted.
Ephesians 2:11-13 – "Wherefore remember, that you being in time past Gentiles in the flesh... that at that time you were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise... But now in Christ Jesus you who sometimes were far off are made nigh by the blood of Christ."
Paul speaks about the covenants of promise. We know from his other letters that he is thinking of God's covenant with Abraham, not His covenant with Israel. As Paul argues in Romans 4, God promised Abram that he would be the father of many nations, which is why God changed his name to Abraham. Specifically, all those who are "in Abraham" will receive the blessing. And Paul argues that to be "in Abraham" is to have the faith of Abraham -- believing that God can bring the dead back to life.
Nothing is said about keeping the Ten Commandments.
We know we are part of this spiritual nation because God has given us His Spirit, which allows us to call Him our Father.
Romans 8:14-15 – "For as many as are led by the Spirit of God, they are the sons of God. For you have not received the spirit of bondage again to fear; but you have received the Spirit of adoption, whereby we cry, Abba, Father."
"God sent forth his Son... to redeem them that were under the law, that we might receive the adoption of sons... Wherefore you are no more a servant, but a son; and if a son, then an heir of God through Christ."
By accepting Jesus, you have received a new name and a new heritage. You are part of the "whole house of Israel" that God is preparing for His eternal kingdom! Ezekiel 37:11-14
Absolutely, we are part of God's household, and we will receive our inheritance, but this doesn't make us Israel.
