The fire of love for Christ burned so hot in Francis that he longed to give all that he was to Christ through martyrdom. I am struck by the phrase "set on fire therefore by that perfect charity which drives out fear". There is something underneath the words that speaks of a passion beyond words. It echos of an encounter with Christ at the depth of being, which, like a summons propelled Francis to abandon all for the sake of his Beloved.
This encounter with the Divine demanded all of Francis and he longed to live that out and to help other souls by his example. He lived beyond ego, beyond selfishness and beyond desire. All he desired was his Beloved and he saw his beloved in all things, especially in the souls for whom his most precious and holy Beloved Lord Christ Jesus gave his life to save. Francis did all he could to serve the Gospel message.
