What does it really mean to have authority? If you were to break it down a little more, you would see that the keyword to "Authority" is “Author.” An author is not a person who doesn’t know what’s going on. They control the complete outcome of every conflict, discovery, and conclusion of the story. Authors exercise in power. Authority is a position that you have because you are in Christ Jesus. He gave us the same authority as Him because He is the author and finisher of our faith!
Matthew 10:1 (NKJV) – “And when He had called His twelve disciples to Him, He gave them power over unclean spirits, to cast them out, and to heal all kinds of sickness and all kinds of disease.”
