Question: How to distinguish correct, saving work of faith from delusional work?
Answer: Of course, only a spiritually experienced person can do this - can determine what work is performed by someone. And for ourselves, we must learn this truth: you do not need to invent works. When a person comes to repentance, he naturally begins to correct his life, his behavior is not invented, not fabricated, but forced by the way of life, by the struggle with his passions. Such work is required by itself and taken for granted. It does not make arrogant, does not give a person a reason for self-conceit and self-exaltation, but only leads him along the path of repentance and correction.
Meanwhile, the delusional work is usually far-fetched and bright. And it is especially necessary to emphasize: it is “great”, but short-lived: it is completely abandoned with the course of time. It alternates with self-indulgence and relaxation: “You worked hard - you can relax! Work hard play hard”. A man has accomplished something: fasting, or vigil, or prayer, or a certain number of bows - that's all, now he is “having a rest”.
These are signs of a harmful deed, leading, to a greater or lesser extent, to delusion.
Question: What is delusion?
Answer: In brief: when we consider to be good something that is not good. When we take the demonic action or our heated blood for the action of the grace.
