As a child there were few people in the world as intimidating as Mike Tyson. No one messed with Mike Tyson. He was small, mighty, strong and fearless - all things that I desired to be physically. As I grew older I discovered that I was not the physical specimen that Tyson was so they physical strength was out of the question. However, I applied these same desired attributes toward my spiritual formation. That is I wanted to be as mighty, strong and fearless so that even the demons would be afraid to mess with me.
As I come into my thirty-sixth year of life, I can proudly say that demons do not mess with me, but not because I am strong and mighty.
Abba Poemen said to him, "Is it the demons who attack you? It is not the demons who attack me. When we follow our self-will then our wills seem like demons and it is they who urge us to obey them. If you want to know who the demons really attack, it is against Moses (another Abba) and those like him." - The Desert Fathers by Benedicta Ward
I am less like Mike Tyson to the demons and more like "Glass Joe" - which is why the demons don't mess with me. I am easily overwhelmed by my own ego and self will to be any threat to a demon.
