I am reminded of one of my favorite friendship quotes by C.S. Lewis:
"In friendship…we think we have chosen our peers. In reality a few years' difference in the dates of our birth, a few more miles between certain houses, a choice of one university instead of another... 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 ceremonies has been at work. Christ, who said to the disciples, “You have not chosen me, but I have chosen you,” can truly be say to every group of Christian friends, “You have not chosen one another, but I have chosen you for one another.”
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 beauty of others."
