if that word works for you, as a ray of light. Think of all the earthly and worldy distractions as awnings that block the light. Think of trying to move out from under the awning in to the light. Faith is what keeps us from commiting suicide or taking revenge or turning into a cynic when life deals us shit.
Not to be dismissed either is the idea that when you have faith and ask for help, you find that maybe you are attracting others to you who feel the same way. Others that can help, assist or point out the error of your ways (thinking) to you.
