'...in Friendship...we think we have chosen our peers. 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 our 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 Ceremonies has been at work. Christ, who said to the disciples "Ye have not chosen me, but I have chosen you," can truly say to every group of Christian friends "You have not chosen one another but I have chosen you for one another."'
CS Lewis, The Four Loves, p.83.
