No. I say no. They are not God's people. The whole idea of a single race of people being God's people is nothing more than racism and blasphemy. It's goes against the very tenets of the Christian faith.
They are in no way God's people. Would God's people continually wage war? Would God's people steal what doesn't belong to them? Would God's people kill innocent women and children? Would God's people lie and deceive to order to be keep from justice? No. But Israel does all these things, they are not God's people. You believe they are God's people because you have been deceived my false prophets like Hal Lindsey and others like him, you have turn your back on your fellow Christians in Palestine. It's you who is condoning evil, it's you who is condoning theft and murder and war instead of peace and justice.
Is it Isaiah 66 condoning theft and murder and war instead of peace and justice? If so, God is condoning theft and murder and war instead of peace and justice, the same God, who never changes, who gave us Salvation and an eternity in Heaven.
Your fallacy is in many places throughout the holy scriptures. Also, if the idea of one people being God's people is racism, then God is a racist. The same God who gave us equality in the Kingdom of God. That's a fallacy of yours that you'll most likely turn around and use against me, as some proof that I'm a racist or some such ludicrous charge.
As for my fellow Christians in Palestine, I worship God, not my fellow Christians in any country. The scriptures say Israel belongs to the Jewish people, God gave it to them, specifically THIS Israel.
