The biblical sense of "power from on high" are characteristics like courage, resilience, graciousness and, above all, love. Another list is Paul's "Fruits of the Spirit" from Galatians 5:22-23.
...the fruit of the Spirit is love, joy, peace, kindness, generosity, faithfulness, gentleness, and self control.
None of these has anything to do with winning or gaining power over others. They are not so much about "end results" as they are "ways of being," and that is perhaps the most important distinction between "power" as we tend to conceive it, and biblical "power."
The other important distinction is that "power from on high" is just that, from elsewhere. It is a gift. In biblical terms, it is grace, and so it is not something which we must conjure up in ourselves but something which we must be ready to receive and exercise sometimes despite our inclinations.
Which is to say, power from on high is a promise, something with which we are clothed.
