The current citizens of the Jewish State of Israel, call themselves; Israelis.
Jesus calls them; of the synagogue of Satan, Revelation 3:9 And Paul calls them not Jews at all; Romans 2:29
We Christians are the Israel of God, the Overcomers for Him.
Incorrect. Jesus does not call the entire nation of Israel - whom Paul emphatically states God has not abandoned in Romans 11:1 - the synagogue of Satan.
Jesus specifically called the hypocritical Pharisees, who were not living righteously by following the law they demanded everyone else keep, that they were of their father the devil, and had made their synagogue into a synagogue of Satan - just as He also called Peter Satan for trying to talk Him out of dying on the cross.
