The First And Second Fear

Ὅταν δι' ὑπομονῆς καὶ εὐχῆς λάβωμεν τὴν ἄνωθεν δωρεὰν, τότε διῶξαι δυνάμεθα τοὺς ἀοράτους βαρβάρους, καὶ ποσιῦνται τρόμῳ ὑπὸ τοὺς πόδας ἡμῶν. Φησὶ γὰρ καί τις προφήτης, ὅτι Οὕσπερ τὸ πρῶτον ἐφοβεῖσθε, φοβηθήσονται ὑμᾶς. Ἅγιος Νειλος, Βιβλιον Πρῶτον, Ἐπιστολὴ ΡΠΖ ' Γιγαντιῳ Διακονῳ Source: Migne PG 79 153b

When by endurance and prayer we receive gifts from above, then we are able to put to flight the unseen barbarians, and they fall in fear before our feet. For a certain prophet says: 'As you first feared, they will fear you.' 1 Saint Nilus of Sinai, Book 1, Letter 187, to Gigantios The Deacon 1 Isaiah 33.7
