Christians can get caught up very easily into power trips. It is very subtle. But stop and think. Generally we define it as the ability to do something, as being extra strong, etc. What I referred to in the previous paragraph should give you a clue.
Power comes from authority.
Ever known a policeman to just tell you to obey the laws. Once in a while he will do that, but he also, if need be, will enforce the laws. He has the power to do so-why because of the authority behind him. If police could not enforce laws, no one would obey them. This should tell you which comes first.
