Have you ever heard of someone exceeding their usual level of authority in a crisis to intervene effectively to avoid disaster? They are generally recognized as heroes for being bold and decisive when it was necessary to save the day. In an emergency you can assume the authority you need to get the job done.
Do you apply this same principle to your work in my Kingdom? Yet I have already given you the power of attorney to act in my name, not only in emergencies, but in things you encounter on a routine daily basis. You don’t need any more authority than you have. Go and heal the sick, raise the dead, cast out devils, and proclaim the good news of the gospel to the lost.
