my opinion Revival and Repentance they goes hand in hand. Revival is to bring something back to life. Repentance is feeling sorry, changing one’s behavior, new way of living. In order to come live your life in christ Revival and Repentance is very important with being born again in the newness of Christ. This maybe getting off subject but Conviction and Change same thing you can’t have one without the other. No conviction it will be no change.
