Grace and the Heart
Grace engraves on the heart of the children of light the laws of the Spirit. They must not therefore draw their confidence only from the Scriptures written in ink, for God's grace also inscribes the laws of the Spirit, the celestial mysteries, on the tables of the heart. The heart, in fact, directs and rules the whole body. Once grace possesses the pastures of the heart, it reigns over all its members and all its thoughts. For therein is the mind and all the thoughts of the soul and its hope. Through the heart, grace passes into all the members of the body.
