No. The Israel of God according to the Bible is anyone in Christ who is a new "creation":Israel has not been cast away and I dont worship Israel
The Israel of God is believing Israel NOT the church
Galatians 6:15-16:
For in Christ Jesus neither circumcision nor uncircumcision means anything, but a new creation.
16 And as many as walk according to this rule, peace and mercy be upon them, and upon the Israel of God.
(The following comments are from AI):
"The Israel of God" (Israel of God):
Jewish Believers:
Many commentators argue this specifically refers to ethnic Jewish believers in Jesus who are not part of the legalistic "Judaizers".
Spiritual Israel:
Others interpret this as a designation for the entire Church, comprising both Jew and Gentile, as the true heirs of the promise.
( End of comments)
While it is possible to interpret " Israel of God" as jews that become Christians, Spiritual Israel in scripture points to Jesus Christ and all who believe on Him.
Because there is no difference between Jew and Gentile. Period.
