'Why do you hide your face?'
The book of Psalms contains many songs of comfort and encouragement, but there is a voice within the Psalms that is far from reassuring. Instead of projecting heavenly peace into earthly confusion, these other songs are cries of pain and anguish.
I find that a great help. When I struggle with crises my depression is often compounded by the suspicion that I shouldn't be feeling this way. And as I open the book of Psalms, what do I find? These great heroes of the faith went through crises that made them hurl angry questions at God. When I see this, it helps me understand that I'm not a dismal exception to the rule that Christians are strong and joyful all the time.
