This thought occurred to me
It is scriptural that demons know there is a hell
Why then do they continue to do what they do?.
I think they believe they will win
After all, isn't that why they left in the first place?
So, when we remind them of hell, sparks fly
I do recall a story by Richard Wormbrandt of seeing an angel that didn't look so good
He asked the anger, why are you so weak
The angle said that he was a fallen angel who had repented
I hope so
After all, how many second chances have some of us had.
 
So, when doing spiritual warfare, it is appropriate to remind them of hell.
Because they think they will win, they need this road out ahead reminder.
In other words, hands off or else.
