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.
St. Seraphim of Sarov
