St. Theophan the Recluse: . . . if we undertake to cure ourselves, then we will be able to do something about it.
“If [the disease of sin] is natural, then it cannot be cured. Thus it would remain always, no matter how hard you worked to rid yourself of it. If you accept this thought, you will lose heart, and say to yourself: this is how it is. For this is that woeful despair, which, once it has been introduced into people, they have given themselves over to lasciviousness, to work all uncleanness (Ephesians 4: 19).
“I shall repeat again: Maintain the conviction that our disorderliness is not natural to us, and do not listen to those who say, ‘It is no use talking about it, because that is just how we are made, and you cannot do anything about it.’ That is not how we are made, and if we undertake to cure ourselves, then we will be able to do something about it.”
