Let’s look at the Gospels of Jesus Christ in the New Testament and examine the attitude of Jesus Christ toward Israel.
Jesus Christ had no respect for the Jerusalem Temple and its authorities, and, in fact, it was the Jerusalem Temple authorities who condemned Jesus Christ to death, produced false witnesses to get Him charged criminally, pressed for warrants for His arrest, got Him convicted in the court of law, using lying witnesses, and had Him imprisoned and killed on the cross.
Matthew, Mark, Luke, and John spend considerable space condemning the Jews as a people for crucifying Jesus Christ. Book of Acts in the New Testament thematically upholds the Gospel Truth that Jews killed Jesus Christ.
Thus, anyone who supports the Jewish nation of Israel has chosen to stand against the Truth of the Gospel that Jews killed Jesus Christ and that Jesus Christ cursed Jewish cities and condemned Jerusalem as a killer of God’s messengers and Jesus Christ Himself.
So, YES, in light of the Gospel Truth against Jews and the Jewish nation, all Christian Zionists should expect to find themselves in eternal damnation in Hell for being a traitor to Christianity and the Gospels of Jesus Christ.
Jews killed Christ, according to the Gospels, and Jesus Christ clearly stated that those who are not with Christ are against Christ. Christ condemned Jewish cities, Jerusalem, Israel, and the Jewish people.
