I promise you I won't die. ~Samwell Tarly s4e9
Adam Rifkin stashed this in Game of Thrones!
I really hope that promise was made to the viewers as well as to Gilly!
Promises to the viewers don't mean much -- in the previous episode Oberyn promised not to die.
Another reason Sam won't die: He promised Lord Commander in season 3 he wouldn't.
In the books:
As he lies dying he asks Sam to send word to Jorah Mormont, his dying wish being to forgive his son of his crimes and let him come home to take the black, relieving him of his exile.
Also relevant: When Lord Commander Mormont gives his Valyrian sword to Jon Snow in season 1.
You'll appreciate this, too.
