HO are children of light, serve the New Testament in the Holy Spirit, they don’t learn anything by men, God himself teaches them, His very Grace writes in their hearts the laws of Spirit. They don’t have to be informed only by scriptures written in ink, but God’s grace writes in the paper of the heart the laws of the Spirit and the heavenly mysteries. Heart is the leader and king of the entire corporeal organ, and when Grace takes hold of heart’s fields, Grace becomes the king of all members and of all thoughts. Heart is the place of the mind and of all the thoughts of the soul and of her hope, and because of this, Grace is transfused to all the members of the body.

Ἡ γὰρ καρδία ἡγεμονεύει καὶ βασιλεύει ὅλου τοῦ σωματικοῦ ὀργάνου, καὶ ἐπὰν κατάσχῃ τὰς νομὰς τῆς καρδίας ἡ χάρις, βασιλεύει ὅλων τῶν μελῶν καὶ τῶν λογισμῶν· ἐκεῖ γάρ ἐστιν ὁ νοῦς καὶ ὅλοι οἱ λογισμοὶ τῆς ψυχῆς καὶ ἡ προσδοκία αὐτῆς, διὸ καὶ διέρχεται ἡ χάρις εἰς ὅλα τὰ μέλη τοῦ σώματος…
