Should Christians be Involved in Politics?

Good advice on the subject from Madeline Crabb at Renew America:

Charles Finney once said that the Church must take right ground in politics, and that God will bless or curse America according to the course Christians take in politics. Finney asserted, "Politics are a part of a religion in such a country as this, and Christians must do their duty to the country as part of their duty to God."

Christians are instructed to carry their principles, their salt and light, into the whole world, which includes the world of politics. If Christians aren't engaged in this arena, then the ungodly will be. If Christians don't speak up to be heard, then the ungodly will.

If Christian principles don't affect public policy and lawmaking, then ungodly principles will. It is a simple fact that godly principles will become a part of public policy, and yes, politics, only if godly people are involved in these areas.
