Wow.
I surely can't come up with anything more powerful than the scene from Desdichado's post, but I'll go ahead and share one of my own favorite scenes ever. It's from the movie, "The Crow."
It starred Brandon Lee (the son of martial arts legend Bruce Lee,) who was tragically killed during the filming. Brandon was quickly becoming my favorite actor at the time, so it was pretty crushing to me when he died.
In the movie, he plays Eric Draven, a young musician who, along with his fiancee, are brutally attacked and murdered. Eric comes back as a kind of spirit of vengeance and seeks out their killers. I won't show the clip here, as I'm sure it will be seen as too violent, so I'll try to describe it instead.
When Eric confronts a particularly vicious participant known as Tin Tin, whose expertise is throwing knives, this villain hurls an especially biting insult regarding Eric's murdered fiancee. Eric, overwhelmed with emotion, is vulnerable and distracted, and as the two physically spar, Eric loses his hold in the fight, and starts to crumble. In the meantime, Tin Tin takes out his knives, telling Eric that he "wants him to meet a few friends of mine," and starts bragging that, "They. Never. Miss."
Well, you can guess what happens next. Tin Tin throws a knife, then misses; he throws another, then he misses again, as Eric knocks the knife away just as easily as swatting away a fly. In the meantime, Eric has begun to turn the tables on Tin Tin, taunting him with, "Try again. Try harder!!!"
Provoked beyond reason, Tin Tin finally screams in frustration as he hurls his last knife at Eric with all his might -- and Eric catches the knife between his hands in mid-air, with the blade squarely pointed towards the middle of his face.
He holds the knife for a second, then takes the handle and throws it right back at Tin Tin, pinning the criminal to the wall with his very own weapon, along the pride that Tin Tin had carried behind it.
Eric promptly says (in one of the most famous lines from the movie), "Victims. Aren't We All."
The reason I love this scene so much is because in my most grandiose thoughts, I picture this as an illustration of myself facing the devil when he's hurling his most vicious spiritual attacks at me. He's throwing all his best tactics, over and over, confident that he "won't miss."
And my constant prayer is that God will please make me fast enough and strong enough to begin to be able to dodge the knives instead of being hit by them, until eventually, I might reach a point where I can catch one in mid-air... and throw it right back at him.
To me, this scene is a perfect visualization of the prayer: "Lord, help me kill whatever is trying to kill me."
