'Power' in the Bible

But that ye may know that the Son of man hath power on earth to forgive sins, (he saith to the sick of the palsy,)

And to have power to heal sicknesses, and to cast out devils:

And he called unto him the twelve, and began to send them forth by two and two; and gave them power over unclean spirits;

And he said unto them, Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.

And Jesus answering said unto them, Do ye not therefore err, because ye know not the scriptures, neither the power of God?

And then shall they see the Son of man coming in the clouds with great power and glory.

And Jesus said, I am: and ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
