I used to be a Zionist. I also used to be a conservative. My theology required that there be a rapture, and that the Jews have a homeland in Palestine before the rapture. I believed a lot of these things, and it was odd to me that other Christians did not.
But then I discovered liberty. The kind of liberty that set me free from homage to the government. Conservatives believe in the government. They believe in power. When I gave up government, I realized I also had to give up the government of Israel. I believe that the Jews are God's chosen people and He still wants to acomplish some things through them, but not necessarily through the state of Israel.
