The man who thinks he can carry on his business life, or his political life, or his social life, without God is to that extent an irreligious person. The teacher who thinks that his relation to God does not affect his teaching of chemistry, or his interpretation of European history, is to that extent an irreligious person. The consistent Christian will realize that his religion is the ruling principle of all his life, and that there is nothing in life which can be isolated from his relation to God. - Johannes Geerhardus Vos
