I think it is very superstitious. Also arrogant, in a way. Witnesses say "Jehovah willing" about the smallest things. I always thought that was funny. Sure, the supreme god of the universe will be personally deciding whether or not your boss gives you a raise. Whatever. Actually, that kind of thinking really messes with your head, because if you really believe it then everything bad that happens will make you wonder if you really have Jehovah's blessing, then to wonder what you did to lose his blessing, then to get depressed, etc.
