Should Christians engage in politics?

Dr. Martyn Lloyd-Jones: "The biblical view of man is that he's to function in society. For instance, Paul's teaching is that the powers that be are ordained of God, that magistrates and all are ordained by God. There are two elements in my position. Man fundamentally needs this gospel, which can renew him and renovate him and make a new man of him. But in the meantime, he's a believer in law and order, because sin must be held within bounds. If you don't have magistrates and punishment and so on, you'll get chaos. And I think we are witnessing a good deal of it at the present time. But this is a part of the whole Christian position. And Christian people in the past have played their part in politics and in various other aspects of Christian life. Unfortunately, in the last hundred years or so, I agree they have been somewhat guilty of the charge that you bring against them. But a number of us, and by now I think that's more or less gone. I find today that most evangelical Christians are very much concerned about the social implications. They're laying great stress upon it."
