Goodness And Understanding

Ὅταν ἄνθρωπος ἄνθρωπον ὠφελήσῃ ἐν λόγοις ἢ ἐν πράγμασιν, Θεοῦ εἶναι τὴν χάριν νοείτωσαν ἀμφότεροι. Ὁ δὲ μὴ συνιὼν τοῦτο, παρὰ τοῦ συνιέντος ἐξουσιασθήσεται. Ἅγιος Μάρκος ὁ Ἐρημίτης, Περὶ Νόμου Πνευματικοῦ Source: Migne PG 65.913d

When a man is of help to a man by word or deed, let both think on the grace of God. He who does not understand this is overthrown by his understanding. Saint Mark The Ascetic, On The Spiritual Law.
