Quaker Beliefs

Quakers, more properly known as the Society of Friends, believe that a piece of God is within each of us. (God puts into each person (and each member of His creation) a piece of Himself, of His Spirit.) 

This piece of God--sometimes referred to as an "Inner Light" or the "still, small voice of God"--can serve as a spiritual guide.  

If one listens to this "voice," one can have first-hand and immediate knowledge of God and His will for one's life.  

Members of the Society of Friends believe that undue emphasis on worldly pursuits and achievements in one's outward life creates inward "noise" which distracts a person from listening to the true voice of God within.  

And so to better listen, one seeks to live an "inward life" of quietness and simplicity in all things--in dress, in worship, in abode, behavior.  

In addition, as John Woolman writes, one seeks to live a life where "practice doth harmonize with principle."  (If one's actions (practice) are in conflict with one's principles, the noise this conflict creates will be distracting and drown out the whisperings of that "still, small voice of the Spirit.")

Finally, most Friends believe that as one becomes spiritually attuned to the "Inner Light" or piece of God within, one can truly discern between good and evil and make proper choices.  

In addition, this attunement allows a person to feel a unity with all of creation since God reveals himself through, and lies within, all of His manifestations.
