Evil has no natural existence and no-one is evil by nature. Because God did not make anything evil. If people desire evil, then what’s not actually there is called into existence, because that’s what they want. So, by the remembrance of God, we have to disregard the habit of evil. Because the nature of good is more powerful than the habit of evil. That’s because good exists, whereas evil doesn’t, except when we do it.
“Saint Diadochus of Photice”
