I am not sure how much discussion with amount from this thread. I am not sure that there are any Christians here that believe that as Christians we be involved in politics and the government.
Either way I am going to refer once again to another Greg Boyd sermon. He talks about what the Kingdom of God truly is and what it should include and most importantly how as Christians can we live in the Kingdom of God.

Atheists, I think this might be an interesting watch for you as well just to better show you what the bible teaches on how Christians should actually be living their lives.
