The novelist Graham Greene told the story of a group of nuns, whose lives were dedicated to taking care of lepers. When eventually they learned that a cure for leprosy had been discovered, they actually found themselves quite disappointed. Their identity had become so consumed with standing against the disease that, without realizing what was happening, they had begun to collude with it, needing it for their sense of purpose, and now resented that healing was coming to their patients from another source other than them.
It reminds us of the danger of defining ourselves by what we are against and forgetting what we are for. That’s why Jesus told his disciples that whoever was not against them and what they stood for was actually for them. Love is of God wherever it shines.
