Should Christians be concerned with faith and evangelism and not political affairs?

In answering this question, American Crossroads provides a thought-provoking look at what it means to submit to the governing authorities of the United States of America. Just as God called for Christians to submit to the Roman government that forced its will upon the people (Rom 13:1), so too is God calling for us to submit to the existing form of government in the United States, a government that lives and thrives upon the will and involvement of people. Today, by submitting to the government, Christian citizens are led to influence the American political process that depends upon the involvement of all citizens for its well-being and survival.
