Enduring

Every warrior of the light has been afraid to enter a combat.
Every warrior of the light has betrayed and lied in the past.

Every warrior of the light has lost faith in the future.
Every warrior of the light has trodden a path which was not his own.

Every warrior of the light has suffered because of unimportant things.
Every warrior of the light has doubted that he is a warrior of the light.

Every warrior of the light has failed in his spiritual obligations.
Every warrior of the light has said yes when he meant no.

Every warrior of the light has hurt someone he loved.

That is why he and she are warriors of the light:

They had endured all this without losing the hope to improve.
