My groaning has worn me out. All night long my tears flood my bed. My bed is wet because of my crying.
Pouring out his heart, David was completely honest with God. We can be honest with God even when we are filled with anger or despair because God knows us throughly and wants the very best for us. Anger may result in rash outward acts or turning inward toward depression. But because we trust on our all-powerful God we don't have to be victims of circumstance or be weighted down by the guilt of sin. Be honest with God, and he will help you turn your attention from yourself to him and his mercy.
