Couldn't agree more.
First, I think that all people are happier if the sense they are in service to a power greater than themselves. For many that's religion.
For others it can be raising kids. For others it's philanthopy, volunteering, and so on.
The life lived for it's selfish self is not very gratifying.
Religion is one way some people can sense an understanding, a protector, with the added advantage that it gives some mortal beings an opportunity to exercise power and control.
Seductive, especially as power and control are aphrodisiacs.
