There is a difference you know. A very important difference too I
might add. There are people, well meaning sincere Christian people,
who fail to see that truth clearly and that failure leads to many
errors in doctrine and practice.Authority is one thing and power is
quite another.
POWER: in the Greek is the word "dunamis" from which we get our word
for dynamite. It means energetic power, explosive power, or a
demostrative power.
AUTHORITY: on the other hand is a completely different word in the
Greek "exousia". It is a shame that in English we make no such
distinction. Even in the translations which should have known better
use the translation of the two words interchangeably even arbitrarily
so that the truth conveyed in the original language is lost. Authority
means right, privilege given to someone by another. It refers not to
power but to position!
A policeman cannot say that he has power (dunamis) to stop traffic. He
would have to be incredibly strong to stop even the smallest of cars by
his own strength. Though he has not the physical or personal strength
to stop traffic he is given authority under the law to commandeer
traffic. He can literally stop traffic by his power (exousia), that is
his right and authority.
To be sure we do not have power (dunamis) over Satan. We can never by
our effort or energy stop him. Yet we have been given authority
(exousia) over him in Jesus name and by virtue of the testimony that we
belong to Jesus. "And they overcame him (Satan) by the blood of the
Lamb, and the word of their testimony." Rev. 12:11
When we are given the promise of salvation in John 1:12 we are promised
power (exousia) to become the sons of God. Does that mean that we are
given some special power, strength, or "dynamo" by which we can muscle
our way into becoming a son of God? No! Never! What we are given,
according to the Greek, is "authority" to be called the sons of God.
That means that we are given the right, honor, or privilege to be called
sons of God.
Do you see the difference? It is then a very important difference for
every believer to recognize and learn. Let's learn then what is our
"authority" as believers, and what are our "powers"
It scares me to hear some believers claiming that we have no right to
deal with the devil and quote Jude to prove we have not authority. They
say, since Michael, the archangel, "dared not bring against Satan a
railing accusation but said 'The Lord rebuke you." So we dare not bring
any railing accusations or commands against the devil. This is not a
passage that explains our authority, or limits to our authority. What
it does show us is that Michael understood the difference between his
"power" (dunamis) and his "authority." (exousia)
