I recently arrived at a local hospital to make a pastoral visit. Unlike most patients, however, in this case a nurse had to escort me to the individual's room. In order to get into that particular section of the hospital, she used her identification badge that had a magnetic strip on the back. As she held the strip up to the sensor, the door magically swung open in front of us. While I had an identification badge of my own, mine lacked the proper coding to unlock the door and allow entry. In hospitals, this ensures privacy and protects patients from unnecessary exposure to infection.
As many of my readers know, in the 1990s I served a two-year mission for The Church of Jesus Christ of Latter-day Saints in Brazil. It was among the greatest experiences of my life.
