If you're angry at your doctor, your boss, your relative or your spouse, you can probably sit down and have a productive conversation about it. God, on the other hand, is probably not available to chat.

And yet people get angry at God all the time, especially about everyday disappointments, finds a new set of studies in the Journal of Personality and Social Psychology.

It's not just religious folks, either. People unaffiliated with organized religion, atheists and agnostics also report anger toward God either in the past, or anger focused on a hypothetical image - that is, what they imagined God might be like - said lead study author Julie Exline, Case Western Reserve University psychologist.

In studies on college students, atheists and agnostics reported more anger at God during their lifetimes than believers. A separate study also found this pattern among bereaved individuals. This phenomenon is something Exline and colleagues will explore more in future research, which is open to more participants.

It seems that more religious people are less likely to feel angry at God and more likely to see his intentions as well-meaning, Exline's research found.

And younger people tend to be angrier at God than older people, Exline said. She says some of the reasons she's seen people the angriest at God include rejection from preferred colleges and sports injuries preventing high schoolers from competing.

The age difference may have to do with cultural norms, she said. Perhaps previous generations were taught to not question God, whereas younger people today don't have any qualms about it. On the other hand, it might be that as people get older, they learn how to handle these types of feelings better.

Anger at God can strongly resemble feelings you may have against another person, Exline found. God may seem treacherous or cruel when bad things happen, just like another individual might. Your anger may fester even more when there's no good reason for the negative event, such as a natural disaster or a disease, to occur. And strong, longstanding negative emotions of any kind can lead to physical ailments.

Moreover, distress at God is associated with mental health symptoms. Exline and colleagues found that among cancer survivors interviewed once and then again a year later, those who were angry at God at both points in time had the poorest mental and physical health. But the study cannot prove whether anger at God made them feel worse or that feeling worse made them more angry at God.

Just like with people in your life, you can respect and feel anger toward God at the same time. And you can move toward forgiveness by reframing the way you view the negative event: Perhaps God was not responsible for it or that he acted in that way for a reason.

"When people trust that God cares about them and has positive intentions toward them, even if they can’t understand what those intentions or meanings are, it tends to help to resolve anger," she said.

Granted, these studies aren't definitive; they are steps forward in this emerging field of inquiry and not the final word on the subject.

But we see it in the real world, too. Jeff Crim listens to people's anger at God all the time - specifically, people who are dying. He's a chaplain and bereavement coordinator North Star Hospice in Calhoun, Georgia, and has found that it's important to find a way to express your anger at God in order to deal with it.

Expressing anger can be cathartic, and help you move on, but how you do it is deeply personal, Crim said. Crim himself will speak aloud to God, but others find solace in a trusted spiritual leader or other person to confide in about their anger at a higher power.

"What they need is a safe place to express their anger, to know that their anger has been heard and listened to," he said.
