Peter Tan:  Spiritual Authority Tidbit 12.14

Those who try to overcome demon power without proportionally overcoming the flesh are ineffective. There is no point coming to an intercessory meeting and taking authority over the nations of the world when you haven't overcome sin and the flesh in your life. It is just blabbing words. It does nothing to the devil. It doesn't shake the devil's throne. It is more likely that it just shakes the ceiling.
