Among America's young people, godliness contributes to happiness.
An extensive survey by The Associated Press and MTV found that people ages 13 to 24 who describe themselves as very spiritual or religious tend to be happier than those who don't.
When it comes to spirituality, American young people also are remarkably tolerant - nearly 7 in 10 say that while they follow their own religious or spiritual beliefs, others might be true as well.
On the whole, the poll found religion is a vital part of the lives of many American young people, although with significant pockets that attach little or no importance to faith.
Forty-four percent say religion and spirituality is at least very important to them, 21 percent responded it is somewhat important, 20 percent say it plays a small part in their lives and 14 percent say it doesn't play any role.
Among races, blacks are most likely to describe religion as being the single most important thing in their lives. Females are slightly more religious than males, and the South is the most religious region, the survey said.
The poll's mission was to figure out what makes young people happy. And it appears religion helps.
Eighty percent of those who call religion or spirituality the most important thing in their lives say they're happy, while 60 percent of those who say faith isn't important to them consider themselves happy.
"If you believe God is helping you, then everything else isn't as important and you can trust that there's somebody there for you no matter what," said Molly Luksik, a 21-year-old ballet dancer in Chicago and a Roman Catholic who attends Mass weekly. "Just going to church and everything ... it's very calming, and everyone is nice."
Sociologists have long drawn a connection between happiness and the sense of community inherent to most religious practice. Lisa Pearce, an assistant professor of sociology at the University of North Carolina, said religion can indeed contribute to happiness, but she cautioned that the converse also can hold true.
"It's easier for kids who are happy and have things going well in their life to find the time and energy to participate in religion," said Pearce, co-principal investigator for the National Study of Youth and Religion. "It could be kids who have bad experiences in church end up leaving and being unhappy with religion."
The poll also asked young people to choose between two statements about their views of other faiths.
Sixty-eight percent agree with the statement, "I follow my own religious and spiritual beliefs, but I think that other religious beliefs could be true as well." Thirty-one percent choose, "I strongly believe that my religious beliefs are true and universal, and that other religious beliefs are not right."
The latter statement is more likely to be the position of young teens - 13 to 17 - and those who attend religious services weekly.
Traci Laichter, 14, went to Jewish preschool. Her grandparents are Holocaust survivors. Her family keeps kosher and displays a mezuzah - a little box holding verses from the Torah - on the door of their suburban Las Vegas home.
Her faith is strong and she believes it will last, but that doesn't mean she thinks other faiths are devoid of truth.
"I believe whatever you believe is true to you and it really shouldn't matter what other people think," she said.
