In every province and city, wherever the king’s decree arrived, the Jews rejoiced and had a great celebration and declared a public festival and holiday. And many of the people of the land became Jews themselves, for they feared what the Jews might do to them. [Esther 8.17]
Wait a minute... people who were not Jewish became Jews by choice?
What is revealed in Esther 8.17 supports the fact that "Israel" in the Bible, while certainly identifying the lineage of Jacob and his twelve sons, also identifies people who were not of Jacob's lineage but became "Jews" by choosing to serve the LORD God of Abraham, Isaac, and Jacob - living their lives God's way.
The Apostle Paul actually cleared this up:
For Christ himself has brought peace to us. He united Jews and Gentiles into one people when, in his own body on the cross, he broke down the wall of hostility that separated us. [Ephesians 2.14]
What is revealed here is that being a Jew by lineage was not differentiated from being a Jew by choice because the whole point of being a Jew was about being God's people - not about lineage. Yes, lineage was important for the sake of prophecy in providing a clear line to Messiah, but then, Jesus came to earth. In other words, "God's people" were identified as "Jews" up until Jesus came, and then, after his Advent, "God's people" were identified as "Christ-followers."
The New Testament records this transition from Jews as God's people to Christ-followers as God's people in great detail. It was indeed a difficult transition and, for many, it still has not taken place. People, by and large, have not accepted Jesus as the only way to God... even though Jesus said:
I am the way, the truth, and the life. No one can come to the Father except through me. [John 14.12]
In his letter to believers in Galatia, Paul confirmed this:
Yet we know that a person is made right with God by faith in Jesus Christ, not by obeying the law. And we have believed in Christ Jesus, so that we might be made right with God because of our faith in Christ, not because we have obeyed the law. For no one will ever be made right with God by obeying the law.” [Galatians 2.16]
Yes, the way to God - being "God's people" - for a time required strict human adherence to the rules and rituals associated with being "God's people" (whether they were Jewish by birth or Jewish by choice as seen in Esther 8.17). However, after Jesus died on the Cross, effectively completing the purpose of all those rules and rituals, strict human adherence to Him became what is required to be "God's people."
Jesus said it like this:
If any of you wants to be my follower, you must give up your own way, take up your cross, and follow me. [Matthew 16.24]
Strict human adherence to rules and rituals, even though demanded by God at first, and for centuries, eventually became "man's way" to God. For all who can see it, the rules and rituals were necessary in order to give contrast between man's strict adherence to rules and rituals (that he failed miserably at), or man's strict adherence to Jesus Christ, entirely giving up his own way and depending only upon Jesus' work on the Cross.
Both before and after Jesus' Advent, man's greatest struggle has always been, idolatry: adhering to (trusting in) anything other than, or in addition to, God. God sternly warned of it in the 1st and 2nd Commandments, and Jesus, accordingly, sternly warned of it in Matthew 16.24.
It amazes me how much fuss is made today over being a Jew - almost as if it is a huge distraction - when the only and most important thing on earth is to be "God's people." We hear national leaders and people alike crying out "I stand with Israel!" not realizing that "Israel" was and is God's way, from ancient times, to identify "His people." To stand with Israel is to stand with "God's people" who are distinctly "God's people" by the Way of following Christ.
I do not deny the obvious and clear revelations and manifestations regarding the modern-day nation of Israel. I am suggesting however that "Israel" means more than just a geographic location and people group as Paul wrote in Ephesians 2.14. While, what happens in and to Israel today indeed may have Biblical significance, it very much has symbolic significance to "God's people" the world over. As the Book of Revelation reveals, every living soul who has, or ever will live, will be determined as "God's people" ONLY by Jesus Christ.
I believe much of the confusion about God's people and end times today comes from insistence on differentiating between Israelite and non-Israelite... "God's people" are all "God's people" and there is only ONE way to be "God's people": strict adherence to (faith in) Jesus Christ. That decision to follow Christ, foretold by the decision to become Jews by those who were not in Esther 8.17, is the ONLY Way to God. Anything else man turns to is an idol.
Father, help us to process and accept what the Bible actually says in spite of popular opinion. And, while many may choose to argue about my thoughts here, may they, more importantly, give up their own way, take up their cross, and follow Jesus. He is the ONLY Way to You, Holy Father, regardless of nationality... So be it.
