According to some surveys, given the same living condition, the level of happiness for those who have faith far exceeds those who have not.
Why? It is because the ones having faith can more easily find their identities in a disorderly society as well as refuge for the mind and purpose for their lives. Most importantly, having faith can help people better control their worldly pursuits, knowing somewhat the futility of relying on those for ultimate happiness. Relatively speaking, their desires are less rampant and hence feeling happier in life overall.
