One bold message from the book of Job is that you can say anything to God. Throw at God your grief, your anger, your doubt, your bitterness, your betrayal, your disappointment — God can absorb them all. As often as not, spiritual giants of the Bible are shown contending with God. They prefer to go away limping, like Jacob, rather than to shut God out. In this respect, the Bible prefigures a tenet of modern psychology: you can’t really deny your feelings or make them disappear, so you might as well express them. God can deal with every human response save one. God cannot abide the response I fall back on instinctively: an attempt to ignore God or act as though God does not exist. That response never once occurred to Job.
— Philip Yancey, Grace Notes, p. 348
