This is a quite good Googletranslation of the amazing Song 'Krieger des Lichts' from the German Rockband Silbermond(eng.:Silvermoon)

[link] to the Clip

Be like the river that flows into the sea of iron
The will not be dissuaded, no matter how difficult it is
Even the largest stone he has no fear
Even if it takes years until he breaks

And if your will is asleep, then wake it again
For each of us lies the warrior
Whose courage is like a sword
But the biggest weapon is his heart

Let us rise up
Makes you on the way
To all the warriors of Light
To all the warriors of Light
Where are you
You're needed here
Makes you on the way
To all the warriors of Light
To all the warriors of Light
Here goes to all the warriors of Light

Do not be afraid of your weaknesses
Never be afraid to discover your mistake
Be careful, calm and free
Was also crazy from time to time

Let's not fool yourself, even when made of gold
Do not be blinded, and certainly not by the false pride
Learn to forgive and
Learn how to captivate and liberate

Let us rise up
Makes you on the way
To all the warriors of Light
To all the warriors of Light
Where are you
You're needed here
Makes you on the way
To all the warriors of Light
To all the warriors of Light
Here goes to all the warriors of Light

And he knows his limitations and is still too far
No happiness in the distance, not after he reaches
His power is his belief, nothing more, he is fighting
And over and over again, so he is a warrior

This is a call that goes here
To all warriors
To all warriors

This is a call
And this appeal goes to all the warriors of Light
To all the warriors of Light
Here goes to all the warriors of Light
