" To instruct us in candid honesty, God gave us the book of Psalms — a worship manual, full of ranting, raving, doubts, fears, resentments, and deep passions combined with thanksgiving, praise, and statements of faith. Every possible emotion is catalogued in the Psalms. When you read the emotional confessions of David and others, realize this is how God wants you to worship him — holding back nothing of what you feel. You can pray like David: “I pour out my complaints before him and tell him all my troubles. For I am overwhelmed.” 6 "
