How To Fight The Enemy
Nothing paralyzes the devil more effectively than closing the doors of our souls to the most fertile agents of evil: our imagination and our memory.
Rather than the peace that Christ brings, the devil carries with him the root sins of pride, greed, anger, envy, and lust―using the faculties of our souls as instruments of evil.
In a soul kept open to every memory and welcoming to every imagining it becomes difficult to recognize the difference between what our best soul has wrought and what the devil has brought.
With memory and imagination comes not just evil, but sicknesses of the soul: weariness, sadness, moodiness, and above all, constant distractions from the one thing that matters―our commitment to moving beyond what we can understand to a life with the God who exceeds all our attempts
Keeping the doors closed to memory and imagination frees up our souls for the ascent we have begun.
