“Emotion is what believers mistake most for spirituality. Carnal Christians whose tendency is emotional in character habitually crave sensation in their lives. They desire to sense the presence of God in their hearts or their sensory organs; they yearn to feel a love-fire burning. They want to feel elated, to be uplifted in spiritual life, to be prosperous in work. True, spiritual believers sometimes do have such sensations, yet their progress and joy are not contingent upon these. The soulish are quite different in this respect: with such sensations, they can serve the Lord; without them, they can scarcely move a step.”
