Christianity is not [currently] declining in America. At the New York Times, journalist Lauren Jackson has been doing some searching, thorough reporting for a new series “Believing.” Apparently, 92 percent of Americans say “they hold a spiritual belief in a god, human souls or spirits, an afterlife, or something ‘beyond the natural world.’”

Jackson reasons that people haven’t found a satisfying alternative to religion. She reports that for the last few decades, much of the world has tried to go without God, a departure from most of recorded history. More than a billion people globally and about a third of Americans have tried to live without religion. Studies in recent years have offered insights into how that is going. The data doesn’t look good.

Actively religious people tend to report they are happier than people who don’t practice religion. Religious Americans are healthier, too. They are significantly less likely to be depressed or to die by suicide, alcoholism, cancer, cardiovascular illness, or other causes. In a long-term study, doctors at Harvard found that women who attended religious services once a week were 33 percent less likely to die prematurely than women who never attended. One researcher on the study said, that because “they had higher levels of social support, better health behaviors, and greater optimism about the future.”

Religiously affiliated Americans are more likely to feel gratitude (by 23 percentage points), spiritual peace (by 27 points), and “a deep sense of connection with humanity” (by 15 points) regularly than people without a religious affiliation.

Religion can’t just become another way to optimize your life. Some have tried. Jackson describes secular community gatherings with pop music, morality talks, free food — but “None of us became regulars.” Going for any reason other than faith itself leaves you with little reason to stick around.
