Absolutely.
There's a really cool passage in the Psalms I was reading today, regardless of your opinion of the bible. It's written by David, one of the great warriors of biblical literature. He was called "a man after God's own heart" and he was involved in so much blood shed that he wasn't allowed to build the temple. Here's what he says:
Psalm 18:34-42
He trains my hands for war,
so that my arms can bend a bow of bronze.
You have given me the shield of your salvation,
and your right hand supported me,
and your gentleness made me great.
You gave a wide place for my steps under me,
and my feet did not slip.
I pursued my enemies and overtook them,
and did not turn back till they were consumed.
I thrust them through, so that they were not able to rise;
they fell under my feet.
For you equipped me with strength for the battle;
you made those who rise against me sink under me.
You made my enemies turn their backs to me,
and those who hated me I destroyed.
They cried for help, but there was none to save;
they cried to the Lord, but he did not answer them.
I beat them fine as dust before the wind;
I cast them out like the mire of the streets.
I think it's fascinating to hear a warrior talk about the importance of perseverance, base, exposing the back of the enemy, and most notably the gentleness required for the finest technique in battle.
Violence is the great educator. "How much can you really know about yourself if you've never been in a fight?"
