First off I didn't come up with this I found it in the Paladin forums along time ago. I would love to give credit to the originator but I don't have their name anymore.
"My comrades are my weapons, and I am their shield.
While I draw breath, they shall not perish.
So long as they live, our enemies will fall.
I am defender, protector,guardian;
I am Paladin."
The first time i read that i got goose dumps. OK i admit to being a nerd whole heatedly; but this is how i view an instance, a raid or even just grouping up to do a quest.
