You have been given the word and the spirit, ie, the power, to do those things. It's very near you in your heart and mouth that you may do them, IF you are willing to put yourself, ie, your old man, to death. If you deny that power of God, then you will just have a form of godliness and not be able to do those things.
The Word and the Spirit are God. You do not control Him, He must control you or you fail to be transformed.
