Religion is what YOU make of it.
Duncan McCleod said it best when talking to Joe Dawson in season 4 (I think) "I've been around a long time, seen a lot of things, and met a lot of people Joe, but one thing keeps us going, just one thing." Joe: "What thing is that?" Mac: "Faith Joe, faith." (then he took a big gulp of single malt!!)
Faith doesn't have to be a religious thing. I have faith that I'll have a good year at work and I (am trying to) have faith that I will make my current "relationship" workout, and I have faith that yada, yada, yada.
Even agnostics have faith, they have faith in their believes that we are too dumb to comprehend GOD. So we all have faith in something. I don't care if it's playdough, we all have to have faith in something.
That's my soapbox on faith.
P.S. I've walked out of too many totalled cars, and came out of too many SHADY ass situations smelling like a rose to not believe someone doesn't have an eye out for me. That or I've done some serious good deeds and generated a surplus of karma. Believe me when I tell you, I should have been dead or in jail many a time, but something pulled me through, and it has happened too often to be "luck"
