From a blog on the "dark night of the soul"

Never doubt in the darkness what God has shown you in the light. — Dr. V. Raymond Edman

During such a "dark night of the soul" (the term used by sixteenth-century mystic St. John of the Cross), the Christian can only cling to faith with the will, for the emotions have already given up the fight. Usually, however, the feelings eventually return, and faith is left stronger than ever. — Kathrine Swarts
