Friendship is the Instrument

In reality, a few years' difference in the dates of our births, a few more miles between certain houses, the choice of one university instead of another, posting to different regiments, the accident of a topic being raised or not raised at a first meeting--any of these chances might have kept us apart. But, for a Christian, there are, strictly speaking, no chances. A secret Master of the Ceremonies has been at work...The friendship is not a reward for our discrimination and good taste in finding one another out. It is the instrument by which God reveals to each the beauties of all the others. - C. S. Lewis, The Four Loves
