there is one passage that's always had a lot of meaning to me, especially since i stumbled across it doing bibliomancy (actually, the first time i ever did it). the question i asked what "what am i supposed to do with my life?" and the answer:

jeremian 1:something-something
"and the word of god was made to me, saying, "before you were born, i knew you. while you were in the womb, i chose you to be a prophet to the nations."

not the exact quote, working off of memory here.
