One bold message in the Book of Job is that you can say anything to God. Throw at him your grief, your anger, your doubt, your bitterness, your betrayal, your disappointment–he 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 deny your feelings or make them disappear, so you might as well express them. God can deal with every human response save one. He cannot abide the response I fall back on instinctively: an attempt to ignore him or treat him as though he does not exist. That response never once occurred to Job.
