Leftists have infiltrated everything
It's called Replacement Theology. When God speaks of Judah and Israel, he really didn't mean it,he meant those Christians who think they are Israel.
These groups tend to ignore the Old Testament as canceled out by the New Testament, even though Paul specifically spoke against the Church thinking that it has replaced Israel.
All of God Word will be fulfilled, especially those prophecies pertaining to the restoration of Israel and the choosing of some of the survivors, after the Day of the Lord as priests.
Satan's plan is to destroy Israel, and hence destroy the Word of God and its promises to his chosen people. Even in Revelations it is pointed out that once Satan discovers that he cannot destroy Israel, he will turn his effort against all those who have accepted Yeshua as savior (The Church, or body of believers).
