Why I said he's only human you know??
But what he has believed all these years and what he has been taught to believe about hi beliefs all his life sure would make him sure enough to believe that for his beliefs he's going to be saved.
Maybe (or probably) there's a tickle in the back of his neck making question what's true or not, but I believe that he believes that he's not uncomfortable or even afraid, because of his beliefs he believes you know?
