What is it about anger that might actually be useful? Being that anger is one of the seven deadly sins it's very interesting to note that it can also become a virtue. We are a people blessed with emotions from a Creator, Who Himself is full of emotion. To block or inhibit those emotions can actually be considered sinful. If someone was to murder your mother and you did not have the emotion of anger within you, either you are missing something psychological, or you are in a sinful state. This isn't to say that anger is an emotion which should be fed, instead what is meant is that as long as anger is properly ordered it can drive the soul towards the Divine. The Iron offers what little else in the created world can, a tangible place where channeled and focused anger can drive results.
It was a holy anger which drove today's saints, Isaac Jogues and John de Brebeuf, to risk their lives converting and evangelizing. The anger that Satan still has a hold on this world will drive a man to do marvelous and wondrous deeds. Uniting that intensity with the focus of Christ crucified leads to a fresh and praiseworthy holiness. Men in particular have a tendency to have a temper, if that temper is directed accordingly with the Gospels, the Holy Spirit will have a tool worth using. The Iron can act as an academia of sorts to teach men, young and old, to rightly order that anger to produce results, instead of demolition. So, next time you are in the squat rack remember where that rage is coming from and direct it towards growth.
