Thanks CB-great question- the church is the continuity of God’s preparatory work through the creation and founding of the nation of Israel. Thechurch is founded upon the revelation given to the prophets of Israel and the apostles of Jesus, the messiah of the church is the jewish Messiah, and the God of the church id the God of Israel. The church is not ISRAEL, but has been grafted into the tree Israel (Romans 11) and brought into the “commonwealth of Israel” Eph 2)
None of that negates the promise of 490 years to the Israelites as a specific people apart from the Gentiles. There are still 7 years of that promise left unfulfilled. Unfulfilled prophesy demands that the nation of Israel will for that last seven years be dealt with as a distinct people apart from the Gentiles. That will happen after “the fullness of the Gentiles” has come in. During this “age of grace” there is no distinction between Jew and Gentile. That will change during that last seven years.
