No longer do I call you servants, for the servant does not know what his master is doing; but I have called you friends ... (Jn 15, 15)
(T)HE BEST WAY OF ALL is to serve (God) because he is our friend, because we want to protest our love for him by our actions, and are sorry, sometimes, that he gives us so little chance of proving ourselves worthy of his friendship.
That is what God made us for, his human creatures, to be his friends, his personal friends. Not that he has need of our friendship; for his infinite beatitude would have remained unaltered if no soul had ever been breathed into a human body. But his overflowing Love is constantly forming new reservoirs, as it were, which it can fill with a human love that makes a response, however poor a response, to itself. As the single orb of the sun is reflected anew, whole and complete, by every puddle on the road-side, so in each insignificant human life that all-embracing love of God shines down, as if it had no other scope or aim for its self-fulfillment, and desires as far as our human imperfections will allow it to find its won image reflected there.
