What is a tool?  It is an instrument used to perform work or a service.  It is used by something other than the tool for a useful purpose.  Is that not why you as a soul are having this human experience?  You as a soul being human are a tool of Spirit.  “Make me your instrument” is a most excellent prayer.  Surrender the need to do everything yourself.  The tool does not act alone.  Allow yourself to be used for the greatest possible good and you are living on purpose.
