As the books of Job, Jeremiah, and Habakkuk clearly show, God has a high threshold of tolerance for what appropriate to say in a prayer. God can "handle" my unsuppressed rage. I may well find that my vindictive feelings need God's correction - but only by taking those feelings to God will I have the opportunity for correction and healing.
Philip YanceyWe should feel dissonance; we are, after all, immortals trapped in mortal surroundings. We lack unity because long ago a gap fissured open between our mortal and immortal parts; theologians trace the fault line back to the Fall.
