Have a dialogue. Ask it questions. Use someone else to help you dig into the truth of nagging doubt. There is gold there. Often, that dissenting voice will help to guide you to a greater intention that is more unified with the entirety of who you are.
Intention is intrinsic.
It may be a desire to serve or to make a contribution to the world, or perhaps to change the world for the better. Something greater than ourselves always underlies intention, because it is rooted in the spiritual depths and is inherently compassionate. This was Fuller's overarching intention, which gave his work purpose and meaning and allowed him to make many valuable contributions during his life. Work, whatever it may entail, is a function of one's deep spiritual commitment to a larger whole, and becomes an expression of one's caring and compassion. We are doing the work we are meant to do.
