“Courage isn't having the strength to go on - it is going on when you don't have strength.” 

Like soldiers we often cannot see how the battle is progressing, our immediate experience in the conflict can be encouraging or depressing, frightening or exhilarating. The call is to keep going, to join in suffering and endure.

 We do not have the luxury of questioning why the advance is not going better, complaining about our mission or longing for civilian life.
