We each joked to close friends that the secret to saving a relationship is for one person to become terminally ill. Conversely, we knew that one trick to managing a terminal illness is to be deeply in love—to be vulnerable, kind, generous, grateful. A few months after his diagnosis, we sang the hymn “The Servant Song” while standing side by side in a church pew, and the words vibrated with meaning as we faced uncertainty and pain together: “I will share your joy and sorrow / Till we’ve seen this journey through.”
