Walter Brueggemann on Lament

"Where the cry [lament] is not voiced, heaven is not moved and history is not initiated. And then the end is hopelessness... It makes one wonder about the price of our civility, that this chance in our faith has largely been lost because the lament psalms have dropped out of the functioning canon. In that loss we may unwittingly endorse false self that can take no initiative... and we may unwittingly endorse unjust systems about which no questions can be raised."
