Pray with the Psalms. Whether in the hospital bed or at a prayer service, the most powerful and comforting prayers offered to me were from the Psalms. They don’t cover up the loss—they bring anger and grief before God. “My heart is stricken and withered like grass; I am too wasted to eat my bread.” And yet they bring all of this in petition before the faithful God of the covenant. “Hear my prayer, O LORD; let my cry come to you. Do not hide your face from me on the day of my distress” (Ps. 102:4, 1-2).
