Whatever that means. And there's the rub.

From Barna's latest research, presented in an article titled, Americans Reveal Their Top Priority in Life:

By far the top priority listed by adults - named by half of the population (51%) - was their family. Some segments were especially likely to list family as their highest commitment: people with children under the age of 18 living in their home (74%), adults in their twenties and thirties (67%), those who are married (61%), Catholics (60%), and Hispanics (60%). Several people groups were much less likely to place family at the top of their list. Those groups included people 60 or older (36%), singles (37%), African-Americans (39%), and Asians (39%).

Faith was the runner-up category, listed by 16% of all adults. This included a wide-ranging set of commitments, such as connecting with God, living consistently with one's faith principles, having peace with God, being a committed church member, honoring God, and growing in faith.

Being "spiritual" is trendy, but there's no clear definition of what that means. Is it a belief in God or a god? How is this spirituality practiced? What does it look like?
