The Scriptures teach us the people who claim to be Christians are attached to Israel. If Israel has been replaced, as many today in the churches believe, they themselves would be replaced because they themselves unknowingly have become one with the natural branch! The Church body needs to accept this reality by faith. Non-Jews are the wild olive branches grafted (spliced) into the natural olive tree of the nation of Israel (Ephesians 2: 11-14).
