Yes, Christians who support Israel are insensitive to God the Father who wants justice against the Jews for killing His Only Begotten Son Jesus Christ (The Gospels in the New Testament emphasize this point!). God’s demand for justice against Jews (“Let His blood be on us and our children!”) is perpetual in nature and will not stop until the Second Coming of Jesus Christ.
Supporting Israel is anathema to God because the New Testament emphasizes that it was the Jews that killed Jesus Christ. Jesus Christ directly condemns Jerusalem (the capital of the country of Israel) for killing God’s prophets. Those who support Israel do not care about the Word of God and its condemnation of Jerusalem and Israel in the New Testament.
God will punish Christians and their children and loved ones for supporting the Jewish nation of Israel which killed God’s Only Begotten Son.
