I just read today in 1 Chronicles 11 about the mighty men of David and specifically Benaiah who chased a lion into a pit on a snowy day and then jumped in to kill it. He killed an armed 7 1/2 foot man with a only a club. One man killed 300 men in battle with a spear.
These men were fighters; brave men who were not afraid of life, or death, for that matter.
They make me want to live better. To fight.
We need something to fight for, and we need to fight until its over.
