'Mighty' in the Bible

and [so that you will begin to know] what the immeasurable and unlimited and surpassing greatness of His [active, spiritual] power is in us who believe. These are in accordance with the working of His mighty strength

May He grant you out of the riches of His glory, to be strengthened and spiritually energized with power through His Spirit in your inner self, [indwelling your innermost being and personality],
