Francis A. Schaeffer on Christian ActivismThe God Who Is There, (Downers Grove, IL: InterVarsity Press, 1968), p136.
The fact that [the Christian] alone has a sufficient standard by which to fight evil, does not mean that he will so fight. The Christian is the real radical of our generation, for he stands against the monolithic, modern concept of truth as relative. But too often, instead of being the radical, standing against the shifting sand of relativism,
he subsides into merely maintaining the status quo. If it is true that evil is evil, that God hates it to the point of the cross, and that there is a moral law fixed in what God is in himself, the Christian should be first into the field against what is wrong — including man’s inhumanity to man.
