This is from Philip Yancey’s book The Bible Jesus Read p. 128-129

To whom do you vocalize the most inense, irrational– meaning inchoate, inarticulate– anger? Would you do so with someone who could fire you or cast you out of a cherished position or relationship? Not likely. You don’t trust them– you don’t believe they would endure the depths of your disappointment, confusion…. The person who hears your lament and far more bears your lament against them, paradoxically, is someone you deeply, wildly trust…. The language of lament is oddly the shadow side of faith.
