I think you may be confusing finding one's religion to be meaningful with some kind of need to broadcast it. I feel every instant of my life to be infused by my faith, yet because it is personal and does require me to testify outwardly about it, it doesn't usually make me want to discuss it with others. You don't get to judge whether it means something to me or not...
By you, not by me
> If you every instant of your life is infused by your faith how does it show?
It shows somewhat because I take actions that are in accordance with my faith, but there's no big "tell", it's not particularly easy to distinguish from generally trying to be a good person.
Why does faith have to cause embarrassment or discomfort in front of others, or even be shown to others, in order to "matter"? That might apply to evangelist faith or faiths placing emphasis on proselytism, but does not apply to every faith.
