1.  dunamis = inherent power; the power of reproducing itself: from which we have English dynamics, dynamo, etc. See Acts 1:8.
 2.  kratos = strength (as exerted); power put forth with effect, and in government: from which we have the English theocracy, government by God; aristocracy, government by the best; democracy, government by the people. The Greek enkrateia = mastery over one's self = self-control, or having one's self reined in (from krateia, a rein). This (that is to say, enkrateia) is the only word rendered "temperance", and occurs only in Acts 24:25. Galatians 5:23. 2Peter 1:6, 6.

 3.  ischus = strength (as an endowment), physical strength possessed. See, for example, Mark 12:30.

 5.  exousia = authority, or, delegated power; the liberty and right to put forth power. See, for example, John 1:12.
