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. They are no greater than the
beauties of a thousand other men; by friendship God opens our eyes to
them. They are, like all beauties, derived from Him, and then, in a good friendship, increased by Him through the friendship itself, so that it
is His instrument for creating as well as for revealing.
--C.S. Lewis
