It is the Divine Furnace of Love who loves us tenderly, infinitely. We think of The Divine Furnace in the lives of the saints:
"I understood so well that it is only love which makes us acceptable to God - that this love is the only good I ambition. Jesus deigned to show me the road that leads to this Divine Furnace, and this road is the surrender of the little child who sleeps without fear in its Father's arms." -St. Therese of Lisieux
