Reverence
Sam had never been a religious person, not until he died, and came back to life, in Egypt. Experiences like that, they could change a person.
Still, it was no deity that he held reverence for, but for life itself. Sam understood how easily it could be taken away now, wars had ways of assuring that, and he would never take such a precious gift for granted again.
Sam would cherish every second he was given, every second the members of his large family were given, no pun intended.
It would take him years and years to realize that his family would revere his life even more.
