"Obedience without hesitation"

What does "Obedience without hesitation" mean? Well... we know what obedience is, that means to do what people are in charge of us tell us to do. But what about"... without hesitation"? Does that mean we do it right away? Well thats half of it. It also means that we are to do it as soon as we are told to and to do it without a grumpy attitude because we have to do it. So remember that the next time you are given a cumbersome task to do.
