By Lay Preacher Demetrios Panagopoulos (+ 1982)
A young monk had a question:
"How does Satan perceive someone's noetic prayer and turns away from them, but he does not have the power to know the thoughts they may have within them?"
That night, a certain female Saint appeared to him while he was sleeping, and she said to him:
"Niko (this was his name), you question how Satan perceives someone is praying noetically, while it is God alone who knows the thoughts of someone?
Listen:
Like the stove, which burns wood internally and we do not see the fire, but the heat tells us that the stove contains fire, so Satan may not see your prayer, but because he burns when he approaches you, he realizes that you are united with God, through prayer."
