God is a fire that warms and kindles the heart and inward parts.
Hence, if we feel in our hearts the cold which comes from the
devil – for the devil is cold – let us call on the Lord. He will
come to warm our hearts with perfect love, not only for Him but
also for our neighbor, and the cold of him who hates the good will
flee before the heat of His countenance.
