'Operating' in the Bible

so that you are not lacking in any spiritual gift [which comes from the Holy Spirit], as you eagerly wait [with confident trust] for the revelation of our Lord Jesus Christ [when He returns].

And my message and my preaching were not in persuasive words of wisdom [using clever rhetoric], but [they were delivered] in demonstration of the [Holy] Spirit [operating through me] and of [His] power [stirring the minds of the listeners and persuading them],

Now there are [distinctive] varieties of spiritual gifts [special abilities given by the grace and extraordinary power of the Holy Spirit operating in believers], but it is the same Spirit [who grants them and empowers believers].
