To do things for God, to serve him – that will follow naturally from our love. It is possible to serve God by reminding ourselves that he is our Creator and we ought to do his will unquestioningly. Or we can serve him by reminding ourselves that he is our King and that any homage which we offer to him is only his right. But the best way of all is to serve him because he is our Friend, because we want to profess our love for him by our actions. That is what God made us for, his human creatures, to be his friends, his personal friends.

– Monsignor Ronald Knox
