Beware of anyone who talks a lot about God but not Jesus as the only God. Beware of anyone whose commitment is to country above Kingdom. Beware of anyone who talks of morality but not redemption thru the cross.
Driscoll got a lot of flack for it, but I agree. Although to me, the problem isn't with Beck's Mormonism, although I certainly don't believe in Mormonism. The problem with Beck and the Tea Party movement is that they worship the American Dream more than God.
Now don't get me wrong, I love being an American. However, even since the 9/11 attacks I've seen patriotism turn quickly into what my friend calls "hijack-patriotism," which to me is another from of religions fundamentalism. Hijack-patriotism says, "If you don't agree with us, you are the enemy." For example, back around 2003 if you were against the war in Iraq, it meant that you hated America. Saying, "Give peace a chance" was the same as saying, "I love Bin Laden." Likewise last year if you supported health care reform, it meant you were a Communist. It's religious legalism draped in an American flag.
As American Christians, we need to remember that God is the god of all nations, not just one. One of the most radical things Jesus did was proclaim the Kingdom of God to both Jew and Gentile. There was no longer one chosen people; God now extends His salvation to all people of all nations. Patriotism is good, but national pride should never come before the Kingdom of God.
