One of the greatest weapons we have in fighting off the attacks of Satan and his demon-minions is, specifically, prayer from the heart, especially the heart of the soul – noetic prayer. Such prayer “drives the demons away because they do not want us to win crowns from God in our battle against them” (Met. Hierotheos. 2010. The science of spiritual medicine, p. 237). Genuine noetic prayer causes Satan and his demons to flee rapidly, according to St John Climacus, because they end up feeling “as though burnt by fire” (ibid.) – the fire of the abundance of divine grace.
