One night a mysterious voice asked him, "Who do you think can best reward you, the Master or the servant?" Francis Answered, "The Master." The voice continued, "Why do you leave the Master for the servant?" Francis realized the servant was Count Walter. He left Spoleto convinced God had spoken to him.
From that moment on, Francis began to care for the sick and the poor -- especially the lepers -- convinced that this was what God had called him to do.
