I am worn out from sobbing. All night I flood my bed with weeping, drenching it with my tears. Psalm 6:6, NLT
Pouring out his heart with tears, 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 thoroughly and wants the very best for us. Anger may result in rash outward acts or turning inward toward depression. But because we trust in 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.
