The anger often stems from the belief that God is responsible for bad experiences, according to the research, which is published in the January issue of the Journal of Personality and Social Psychology. But anger isn't an indication that someone is turning his or her back on God, said study researcher and Case Western Reserve University psychologist Julie Exline. "People can be angry at God while still feeling love or respect toward God," Exline told LiveScience. "In other words, the feelings are not mutually exclusive."
