Counsel And Works

Ἄνθρωπος ὑποτίθεται τῷ πλησίον, καθὰ ἐπίσταται· Θεὸς δὲ ἐνεργεῖ τῳ ἀκούοντι, καθὰ ἐπίστευσεν. Ἅγιος Μάρκος ὁ Ἐρημίτης, Περὶ Νόμου Πνευματικοῦ  Source: Migne PG 65 915a

A man gives counsel to another  according to his care for it, and God works in the one who hears according to his faith. Saint Mark The Ascetic, On The Spiritual Law.
