The Christian ought to be extremely interested in politics because the political issues and decisions affect him at the very core of this activity on earth.
Christians are to be the salt of the earth. We have no right to say that politics is dirty, that politicians are crooks, and that we never have a decent choice when we have done nothing to influence politics…
A handful of Christians can have a wholesome effect on politics. To withdraw and retreat from any area of God’s world is to say that God is not sovereign over that area.
