Dr. Martyn Lloyd-Jones wrote:
The greatest test is that the true Spirit always glorifies Christ. Christ is always in the center; He is always given the preeminence. And the true prophet is not the man who talks about experiences and visions and what he has done and seen, but about Christ. And when you have heard Him you do not say, “What a wonderful man”; you say, “What a wonderful Savior!” You do not say, “What a wonderful experience this man has had”; you say, “Who is the Man of whom the Spirit is speaking?” The attraction is to Christ; the Spirit glorifies Christ.
