What is revelation in the spirit?

This kind of revelation is not a vision, a heavenly voice, a dream, or an external force which shakes the man. One may encounter these phenomena and still not have revelation. Revelation happens in the intuition—quietly, neither hastily nor slowly, soundless and yet with a message. How many denominate themselves Christians, though the Christianity they embrace is simply a kind of philosophy of life or of ethics, a few articles of truth, or some supernatural manifestations. Such an attitude will issue neither in a new birth nor in a new spirit. Numerous are these “Christians” whose spiritual usefulness measures up to zero. Not so are those who have received Christ, for by the grace of God they have perceived in their spirit the reality of the spiritual realm, which opens to them like the lifting of a veil. What they today know is far more profound than what their mind has comprehended; yea, it seems as though a new meaning has been imparted to all which they had only understood or comprehended in the past. Now everything is thoroughly and genuinely known, because the spirit has seen it. “We speak of what we know, and bear witness to what we have seen” (John 3.11). This is Christianity. Searching with intellect never delivers men; revelation in the spirit alone gives true knowledge of God.
