Does faith play a role in the garbage man's life every day motivating him to promote a cleaner world?
Does faith keep that dog catcher, that pothole filler, the ditch digger or the roadside construction flagman performing day after day...knowing they are making a difference in everyone's lives and making the world a better place? (Arguably they safely influence/touch far more people lives on a daily basis than we lone EMS workers).
I could list a dozen high level, high power positions and a dozen equally "lower perceived/under appreciated" positions...but the fact will remain that faith is not a driving force in any of them, is not required to perform them, however within that job there will be those who say yes and those who say no.
Your original post to me is indicative of one of the many problems inherent within EMS and that is elevating our jobs unjustifiably to "a calling" or anything along those lines of thinking. This thinking reeks of judgement as it implies anything NOT within our field is much less and not comparable in status or worthiness of respect. "We do so much for so little, family/friends/public just do not understand..." all a load of BS. We do a job because it rewards US, the individual. It makes US feel good, it feeds our ego, it makes us happy...it just so happens that the work we perform has a more openly perceived value to everyone on outside but only because mostly they themselves are too scared, intimidated or repulsed by some of the qualities we posses which allows us to perform our work. On the flip side...THEY have jobs which contribute great value too and I lack the qualities to do THEIR work.
