While imprisoned by the Nazis in Tegal Prison's Cell 92, Dietrich Bonhoeffer wrote a beautiful sermon for the wedding of his niece and his friend (Eberhard Bethge). Bonhoeffer never had a chance to preach the wedding sermon, but this line has continued to challenge and bless many young couples: "Today you are young and very much in love and you think that your love will sustain your marriage. It won't. But your marriage can sustain your love!"
