Yes, evangelical churches which support the secular Jewish nation of Israel offend God because the four Gospels of the New Testament are clear that it was the Jews and the Jewish nation that killed Jesus Christ.
Using human ideology (Dispensationalist theology) to oppose the emphasis of the Gospels of Jesus Christ in the New Testament that Jesus Christ was killed by the Jewish nation of Israel is to oppse God Himself! Evangelical Christian pastors who support the secular Jewish nation of Israel must repent for their evil action of opposing the Gospels of Jesus Christ!
It is important for evangelical Christians to repent and turn away from their evil of supporting the secular Jewish nation that killed Jesus Christ and turn to the road of righteousness of opposing the secular Jewish nation of Israel, as Jesus Christ Himself did in the Gospels in the New Testament. WWJD?
Evangelical preachers in the United States of America, Canada, the United Kingdom, Australia, and New Zealand are absolutely wrong in supporting the secular nation of Israel. These evangelical pastors are opposing the New Testament when they support the secular nation of Israel, because the Gospels emphasize that the secular nation of Israel killed Jesus Christ. They must abandon human ideologies (Dispensationalist theology) which lead them away from the New Testament. They must repent for not loving God with all of their mind!
Supporting the secular nation of Israel is opposing the Gospels of Jesus Christ in the New Testament. It requires repentance!
