Commentaries:
The Holy Spirit is the power of God. It is the means through which He accomplishes His will. Verse 7 teaches us a great deal about this. God the Father is a Personality. He is located in one place at one time, just as we are. But His ability to insert Himself into and affect events anywhere in His creation is contained within the power that emanates from His mind.
It is His Spirit—which emanates from His mind—that enables Him to be everywhere all at once, if He so desires. It gives Him the ability to keep track of all of us. It gives Him the ability to be with a person in Charlotte or someone in Los Angeles or another in Chicago. Wherever we are, He can be there because by His mind He is able to concentrate His attention in those areas.
We lack power like that. We have limited imitations of it. We can concentrate our attention in a very limited way on certain things, events, or places. But He can concentrate His attention in many areas at the same time by the spiritual power that emanates from His awesome mind.
