Greg Boyd posted this profound picture on his blog several months ago. I think this picture beats a thousand words by a mile, but I'll add some meager commentary anyway.
Christianity is not about rules and morals and "being a good person." It's not about democracy, or free markets, or being the world's conscience. It's not even about being right.
The essence of the Kingdom has never changed: love God and love your neighbor. That's it. Pass along the bread and watch it multiply. But what about Social Security? What about the immigration problem? What about Iraq? Good grief - sometimes we spend so much time fixing our neighbor that we have no time left to love him.
Jesus has already set the example, and He didn't set it by running for President. He set it by washing the feet of sinful men and dying on a Roman cross like a common criminal. Everywhere He went, love and healing followed like flowers after spring rain. Christianity doesn't need a constitution - it already has one.
