The Hidden Guardian

Κρυφίᾳ χειρὶ ὁ Θεὸς πολεμεῖ τὸν Ἀμαλὴκ, ὡς λέγει ὁ Μωϋσῆς. Ὁ γὰρ Δεσπότης ἡμῶν ἀοράτως ὑπὲρ ἡμῶν ἀμύνεται τὸν διάβολον· ἡμᾶς δὲ χάριν τοῦ ὀνόματος αὐτοῦ, καὶ τοῦ οἰκείου ἐλέους εὐεργετεῖ, καὶ θάλπει, καὶ οἰκοδομεῖ, καὶ καταρτίζει, περιφράττει τε ἔσωθεν καὶ ἔξωθεν, καὶ περισκέπει, καὶ σώζει ὁ φιλοικτίρμων, καὶ φιλάνθρωπος Κύριος. Ἅγιος Νειλος, Βιβλιον Πρῶτον, Ἐπιστολὴ ΤΚΕ', Κυριακῳ Διακονῳ Source: Migne PG 79 200

With hidden hand the Lord opposed Amalek, as Moses tells. 1 For our Lord unseen wards off the devil from us. For the sake of His name and His own mercy He acts benevolently, and He comforts, and He builds up, and He corrects, and He fortifies us within and without, and watches, the loving and compassionate Lord who saves. Saint Nilus of Sinai, Book 1, Letter 325, To Cyriacus the Deacon 1 Exod 17.16
