I think this song means don't let others surpress your voice even though they have power over you. And don't let others walk over you, you need to take a stance and tell them what goes.
Then there is that religious side of it .. like the lines "Come on you unbelievers, move out of the way, there is a new army coming and we are armed with faith" I'm not a religious person by anymeans .. but it gives you a sence of a higher power, and that we can over come all obstacles thrown in your path.
