When considering our spiritual life, we often tend to view it in an abstract and vague manner, which can make it challenging to discern precisely what actions are necessary for our transformation and spiritual growth.
However, this posed no issue for St. Gregory of Nyssa. In one of his homilies, the saint explains:
“Think of iron, which at one moment is dark and tarnished and the next, once the rust has been scraped off, shines and glistens brightly in the sun. It is the same with the inner core of man, which the Lord calls the heart. It has been in damp and foul places and is covered in patches of rust; but once the rust has been scraped off, it will recover itself and once more resemble its archetype (Jesus). And so it will be good, since what resembles the good must be good itself. Whoever is pure in heart is blessed because, seeing his own purity, he sees the archetype reflected in the image.”
